Hooker LS Swaps in ’67-69 Camaro & ’68-72 Nova Part 4

Click Here to Begin Slideshow In our last segment of the “Stovebolt Shuffle,” we looked at the complete LS exhaust systems Hooker Headers offers for first generation Camaros and third generation Novas. Before that we dug into the matching Holley Performance oil pans for the same combination, and we began the series with a look at Hooker Headers’ engine and transmission mounts – again for an LS-powered Camaro or Nova. This time around, we’ll shift our focus to the nose of the engine – examining the accessory drive system. Holley offers a cool one. Check it out: With more traditional (early engine) swaps, you simply tracked down the production line brackets and, in certain cases, accessories used for the engine you picked. Basically, if you were using a big block and the car was originally fitted with a small block, you’d have to locate the alternator brackets, appropriate water pump, power steering brackets, crank pulley, water pump pulley and sometimes the correct pulleys for the driven accessories (power steering, a/c, etc.). They were all factory parts. You just had to line them up. Enter the LS Swap. Chevy never put LS engines in early Camaros or Novas. That means you can’t go to the wrecking yard and peel off what you need. And while it’s possible to mix and match some pieces, it can be a real pain to fit everything neatly. That’s where Holley steps in. Their accessory drive systems offer clean, economical brackets and accessories for LS engines. Holley notes that these accessory drives look truly at home on any LS engine, and they look as if they came from the factory this way. They’re right! Holley’s complete accessory drive systems come with virtually everything needed for the installation, from the accessories to the pulleys and even the belt. Sounds comprehensive, and it is. The base kit contains the following components: Large case 130 alternator, Corvette style power steering pump, Sanden a/c compressor (R-134a compliant), tensioner assembly, power steering pump pulley, idler pulley, a/c brackets, ribbed serpentine belt, alternator wiring pigtail and OEM style hardware. With this kit, you have to specify the various accessory brackets you need for your application. According to Holley, “The first step is to determine which belt alignment you want to proceed with. This is determined by the crank pulley and often, but not always, the water pump. If clearance to the radiator is an issue, the compact standard spacing common on the Corvette may be preferred. Otherwise, it is most cost effective to retain the existing crank pulley/water pump and space the bracket and other accessories to match. An application specific installation kit (Holley part # 21-1, 21-2, or 21-3) is required for this accessory drive system.” The installation kits break down as follows: 21-1: To fit Corvette/Cadillac CTS-V/G8 water pump – small pulley (1.5-inch) 21-2: To fit GTO/1998-2002 F Body water pump – medium pulley (2.25-inch) 21-3: To fit 2010-up Camaro/all truck water pump – large pulley (3.0-inch) In addition to the installation kit, you’ll need to purchase a water pump for your particular application. The way Holley has engineered the drive system, their brackets fit virtually all-common LS engines regardless of water pump and harmonic balancer offsets reducing cost and complexity. The installation is relatively straightforward (bolt-on), but Holley does offer the following tips when it comes to putting the pieces together: • The P/S pulley must be installed using an installation tool that can be rented at most auto parts stores. Incorrect installation of this pulley may damage the P/S pump internals. When installed, the pulley bore face should be flush with the end of the pump shaft. • The open-faced pulley part 97-152 (included) can be installed onto the power steering pump before the bracket assembly since bolts can be accessed through pulley windows. • When wiring the alternator, install the included 197-400 plug into the alternator. Next connect the yellow wire to switched voltage that is “on” when the key is in the run position. If the vehicle has a “charge indicator light” the yellow wire can be connected to that circuit. • When installing the belt, route it around all of the pulleys except the water pump pulley. While fully rotating the tensioner arm, slip the belt on the smooth water pump pulley last. • Use the serpentine belt supplied if you are using all Holley accessories and supplemental parts. If you are not using all the Holley accessories supplied, or if you have changed the original crank or any accessory’s pulleys, you will have to measure to find the correct belt length. • In order to determine this measurement, perform the following: Once all brackets and accessories are installed, route masking tape or string around the belt path. Leave the tensioner in the un-sprung position for this measurement. Mark or cut the tape/string to length and remove from the pulleys. Subtract 1 1/8” (28 mm) from the measured length to compensate for the un-sprung tensioner position. You will need to convert belt length to millimeters if measured in inches (inches X 25.4 = mm). Go to any auto parts store and ask for a 6PK0000 belt with the “0000” being the length in millimeters. For example, if you measured 2493 mm and then subtracted 28 mm, you would get 2465 mm, and the part number would be 6PK2465. Remember, if you miss on size, the driver’s side idler can be moved to decrease the required belt length by 1/2”. As you can see, it’s a comprehensive package, and like the rest of their LS swap system, the various components look just like the factory put them in place inside your Camaro or Nova. To us at least, that’s the mark of a well-engineered, comprehensive system. Check out the following photos for a closer look.

Here’s a look at a complete Holley front drive assembly. As you can see, it includes pretty much everything you need except for a water pump.

The alternator is a large case 130-amp job – sufficient for most high performance applications (unless of course you have a honking stereo setup, and that’s beyond our scope).

A compact Sanden air conditioning compressor is part and parcel of the major kit. These AC pumps have proven themselves for decades in the hot rod aftermarket.

Holley also includes an OEM style power steering pump. You’ll need a reservoir, but for many applications, a late model Corvette job works perfectly.

Brackets are nice die-castings. They can be polished, plated, painted or powder coated for detailing. Or you can use them as is.

A belt tensioner and a series of pulleys are included with the kit. Holley also includes a serpentine drive belt (not shown).
