I prefer Permatex. I use RTV Black or Blue for the thermostat housing, applying an approximately 3\/8 inch bead to both the intake and the housing prior to installing the gasket and housing. On the intake manifolds, I prefer to use Permatex\u2019s High Tack Aircraft-Grade brush-on sealant. It won\u2019t flake off and get into the combustion chamber and it\u2019s a high-tack product, so it helps to keep the gaskets from moving while installing the manifold.\u00a0 On the manifold ends, I also use Permatex\u2019s RTV Black or Blue, in the specified \u00bc inch bead overlapping the gaskets at either end. This ensures a leak-free seal. You can get both of these from places like Autozone or O\u2019Reilly\u2019s.<\/p>\n<figure id=\"attachment_18596\" aria-describedby=\"caption-attachment-18596\" style=\"width: 638px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/FX-Cleaning-Wheels.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"18596\" data-permalink=\"https:\/\/www.racingjunk.com\/news\/installing-a-new-carb-and-intake-in-your-hot-rod\/fx-cleaning-wheels\/\" data-orig-file=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/FX-Cleaning-Wheels.jpg\" data-orig-size=\"1200,800\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"carb\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;This is my favorite tool for removing gaskets.

So you do have to watch what you&#8217;re doing.<\/figcaption><\/figure>\n<p><strong>Step 1: Remove the Distributor<\/strong><\/p>\n<p>Pop the distributor cap. Set the distributor cap aside, leaving the plug wires attached, unless you\u2019re installing a new distributor and\/or wires. Snap a picture of the orientation of the rotor to reference when reinstalling the distributor (or installing the new one). Loosen and remove the distributor hold down bolt and remove the hold down clamp.\u00a0 Twist the distributor left and right while pulling straight up to remove it. Set it aside so it doesn\u2019t get in the way. Disconnect the harness if you need to.<\/p>\n<p><strong>Step 2: Disconnect the Carb<\/strong><\/p>\n<p>Remove the air cleaner housing and any ducting. Since we\u2019re swapping out the intake and the carb, we don\u2019t need to worry about separating the carb from the intake. Take a picture of the current carb and intake and where the vacuum lines and any electrical leads are connected. Next, label all of them (Ie: front vacuum port on carburetor to third port on vacuum tee on intake, etc.). Now remove all of them and, set them aside. Next, disconnect the throttle linkage from the carb, usually by pulling a c-clip or small cotter pin. If possible, I usually like to wire the linkage or throttle cable out of the way.<\/p>\n<p><strong>Step 3: Remove the Intake and Carb As a Unit<\/strong><\/p>\n<p>Using a 9\/16 inch (usually) wrench or socket, loosen and remove the intake manifold bolts, starting in the middle and working out on both sides. We do this to keep the manifold from warping because if it\u2019s a stock manifold, there are restorers out there that might want to buy it. If you\u2019re lucky, the manifold and carb unit will come out easily with just a little upward elbow grease. If not, you may need to carefully use a small pry bar at the front corners to break the seal.<\/p>\n<figure id=\"attachment_18597\" aria-describedby=\"caption-attachment-18597\" style=\"width: 638px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/27013.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"18597\" data-permalink=\"https:\/\/www.racingjunk.com\/news\/installing-a-new-carb-and-intake-in-your-hot-rod\/attachment\/27013\/\" data-orig-file=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/27013.jpg\" data-orig-size=\"1200,800\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"carb\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Both Holley-Weiand and Edelbrock offer their product lines in a number of finishes.&lt;\/p&gt;\n\" data-medium-file=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/27013-300x200.jpg\" data-large-file=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/27013-1024x683.jpg\" class=\"size-large wp-image-18597\" src=\"http:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/27013-1024x683.jpg\" alt=\"Both Holley-Weiand and Edelbrock offer their product lines in a number of finishes.\" width=\"638\" height=\"426\" srcset=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/27013-1024x683.jpg 1024w, https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/27013-300x200.jpg 300w, https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/27013.jpg 1200w\" sizes=\"auto, (max-width: 638px) 100vw, 638px\" \/><\/a><figcaption id=\"caption-attachment-18597\" class=\"wp-caption-text\">Both Holley-Weiand and Edelbrock offer their product lines in a number of finishes.<\/figcaption><\/figure>\n<p><strong>Step 4: Remove the Old Gasket<\/strong><\/p>\n<p>How you do this will depend on the type of gasket cleaner\/scraper you have. I use a cleaner that resembles a Brillo pad on my drill, but have also used the razor blade type. Whichever type you use, before doing this, cover the lifter\/push rod valley with the clean shop rags to keep pieces from falling into the engine. Make sure you completely clean the old gasket from the manifold mounting surfaces. If you\u2019re using the sharp-edged scraper type of gasket remover, take care to not scratch the head around the ports as it could cause problems with sealing.<\/p>\n<p><strong>Step 5: Install the Intake Gaskets and End Seals<\/strong><\/p>\n<p>Test seat the intake manifold and lightly trace the front and rear ends of the manifold on the cylinder block. This will give you a template for the end seals later in this step.

Next, lightly brush some high tack onto the manifold mating surfaces.<\/p>\n<p><strong>Step 6: Install the Intake Manifold<\/strong><\/p>\n<figure id=\"attachment_18599\" aria-describedby=\"caption-attachment-18599\" style=\"width: 638px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/75187.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"18599\" data-permalink=\"https:\/\/www.racingjunk.com\/news\/installing-a-new-carb-and-intake-in-your-hot-rod\/attachment\/75187\/\" data-orig-file=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/75187.jpg\" data-orig-size=\"1200,800\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"carb\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Edelbrock also makes a fine line of performance intake manifolds for all engines and applications.&lt;\/p&gt;\n\" data-medium-file=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/75187-300x200.jpg\" data-large-file=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/75187-1024x683.jpg\" class=\"size-large wp-image-18599\" src=\"http:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/75187-1024x683.jpg\" alt=\"performance intake manifolds\" width=\"638\" height=\"426\" srcset=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/75187-1024x683.jpg 1024w, https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/75187-300x200.jpg 300w, https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/75187.jpg 1200w\" sizes=\"auto, (max-width: 638px) 100vw, 638px\" \/><\/a><figcaption id=\"caption-attachment-18599\" class=\"wp-caption-text\">Edelbrock also makes a fine line of performance intake manifolds for all engines and applications.<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>Now, carefully lower the manifold into place. Apply a small amount of sealant to the threads of all the manifold bolts. I know the instructions tell you to just apply the sealant to the middle eight bolts, bolt I prefer to be safe rather than sorry, so I apply it to every bolt. I usually place a good-sizes dollop of sealant on a piece of cardboard and roll the bottom \u00bc inch or so of the bolts in it and set them on their heads just prior to installing the manifold. If your car has a throttle linkage\/cable bracket, set it into position-install the two or three bolts that hold it first so it doesn\u2019t shift around. Now, thread the bolts into the manifold bolt holes by hand and tighten them by hand as much as you can. DO NOT use a wrench or ratchet for this.<\/p>\n<p><strong>Step 7: Torque the Manifold Bolts in Sequence<\/strong><\/p>\n<p>One would think that this step is super-easy, but it really isn\u2019t. You have to bounce back and forth and around the manifold to properly torque the manifold bolts to achieve a proper seal. Your new manifold most likely came with an instruction sheet showing the proper torque and sequence. If not, <a href=\"http:\/\/edelbrock.com\/automotive\/misc\/tech-center\/\">Edelbrock\u2019s Tech Center<\/a> has you covered. Just pick a manifold that fits your engine and scroll down to \u201cInstallation Instructions\u201d section to get the final torque. For instance, for a SB Chevy, you\u2019re looking at a final torque of 25 foot-pounds.<\/p>\n<p>Set your torque wrench to approximately half of that, call it 15 foot-pounds. Scroll down on the instruction sheet to the torque pattern diagram and torque each of the bolts to 15 foot-pounds. The torque wrench will audibly click to tell you the proper torque has been reached. Now, set the torque wrench to the final torque, 25 foot-pounds in our case, and torque the bolts to this final torque spec. Be sure to properly follow the torque pattern again.<\/p>\n<p><strong>Step 8: Install the Thermostat and Housing<\/strong><\/p>\n<figure id=\"attachment_18600\" aria-describedby=\"caption-attachment-18600\" style=\"width: 638px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/dey2js.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"18600\" data-permalink=\"https:\/\/www.racingjunk.com\/news\/installing-a-new-carb-and-intake-in-your-hot-rod\/dey2js\/\" data-orig-file=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/dey2js.jpg\" data-orig-size=\"1200,800\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"carb\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Some instructions say you don&amp;#8217;t need sealant on the thermostat housing and gasket.

Install the thermostat where it goes, either between the manifold and the gasket or the gasket and the housing. Properly align the housing and set it in place. Thread the two or three bolts in place and tighten them to approximately 15 foot-pounds. Getting an exact torque here isn\u2019t important; you just need to be sure the bolts are tight enough for the sealant and gasket to do their jobs, but not stretch or break the bolts.<\/p>\n<p><strong>Step 9: Install the Carburetor(s)<\/strong><\/p>\n<p>Thread the carburetor studs into their holes in the top of the intake manifold as far as they will go by hand. Place the carb spacer (if so equipped) and gasket(s) down (gasket, spacer, gasket) and place the carburetor over the gasket, making sure you have the front of the carb facing the front of the engine. For four barrel carbs this usually means the primaries face forward. Place a lock washer on each of the studs followed by a nut. Tighten these in a criss-cross pattern, to approximately 60-80 inch-pounds.<\/p>\n<p><strong>Note: <\/strong>You may have to modify the stock throttle linkage bracket to fit your new manifold. If so, the instructions for your manifold will have an illustration\/template for this.<\/p>\n<p><strong>Step 10: Install\/Attach the Carburetor Linkage and Connections<\/strong><\/p>\n<p>Reattach the carburetor linkage in the reverse of the removal method you used above. Make sure the linkage doesn\u2019t bind up by moving the throttle through its full range of motion. Be sure to attach the throttle return spring and make sure the throttle returns smoothly to closed. Refer to the picture you took in Step 2 above and connect the vacuum lines and any electrical wiring, such as the electric choke, if so equipped. Remove the labels from the now.<\/p>\n<p><strong>Step 11: Reinstall the Distributor<\/strong><\/p>\n<p>Refer to the picture you took in Step 1 above and lower the distributor into place. Make sure it\u2019s fully seated in its opening. Install the hold down clamp and bolt and tighten the bolt just a bit more than by hand. You want to leave the distributor loose enough to be able to move it by hand, but not loose enough that it moves by itself.<\/p>\n<figure id=\"attachment_18601\" aria-describedby=\"caption-attachment-18601\" style=\"width: 638px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/1984.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"18601\" data-permalink=\"https:\/\/www.racingjunk.com\/news\/installing-a-new-carb-and-intake-in-your-hot-rod\/attachment\/1984\/\" data-orig-file=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/1984.jpg\" data-orig-size=\"1200,800\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"carb\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Here&amp;#8217;s another example of a Weiand high-performance high rise intake manifold.

There are tools that you can use for this but chances are you don\u2019t have them and they\u2019re too expensive to buy for a single installation. Tighten the idle mixture control screws by hand until they just touch the seat(s). Now, back them off a quarter turn. Crank the engine up.<\/p>\n<p>Check the ignition timing. If your distributor has vacuum advance, be sure to disconnect and plug this hose first. Set the timing per spec for your engine. Now, adjust the engine idle speed using the screw on the linkage to get the idle speed where it belongs for your engine. This will vary by engine and transmission type, but the average is between 700 and 800 RPM. Recheck the timing and tighten the distributor clamp bolt.<\/p>\n<figure id=\"attachment_18602\" aria-describedby=\"caption-attachment-18602\" style=\"width: 638px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/1802.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"18602\" data-permalink=\"https:\/\/www.racingjunk.com\/news\/installing-a-new-carb-and-intake-in-your-hot-rod\/attachment\/1802\/\" data-orig-file=\"https:\/\/www.racingjunk.com\/news\/wp-content\/uploads\/2015\/09\/1802.jpg\" data-orig-size=\"1200,800\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"carb\" data-image-description=\"\" data-image-caption=\"&lt;p&gt;Beauty and function.

This is an internal part of the carburetor that controls the flow of fuel to the carb so it doesn\u2019t get too low or too high and flood out. On the side of the carburetor, you should see a small sight glass. You want to adjust the float stop screw so the fuel comes to about halfway up that window. A little either way is fine, but you don\u2019t want it to cover the sight glass opening.<\/p>\n<p>On some carbs the \u201csight glass\u201d is actually a screw that you remove. On these the trick is to adjust the float bowl so that the intake of fuel is shut off at the point where the fuel is just starting to dribble over the lip of the sight screw opening. Remember, I said \u201cjust dribbling.\u201d I didn\u2019t mean flowing. A drip or a drop is all.
