Hey, will this cam work ok with a 11.5:1 496?



http://www.iskycams.com/timingchart...._number=396277


The heads are Factory Oval ports, Ported, 2.25x1.88

The Intake is a Weiand Team G

2 1/8 long tubes

No carb yet,

Just worried this will be to much cam..

Is this going to be a drag race engine? Or is this a duel purpose?

I'm going to say that cam would have a hard time to run a SBC, JMHO

slowman

what are you useing the engine for?

longrodsbc

Bracket Racing Mostly, I will drive the car once in a while on the street but my main focus is racing.


The car is a 72 Chevelle so Im quessing the weight is 3600?

I still stand behind what I said,in my last statement,

That is a single pattern camshaft,I wouldn't use it myself,there are alot better special grind camshafts out there,this is one of your "off the shelf camshafts" I go with a special grind cam.

The duration on the cam looks somewhat close,but the lift is a bit away from what that 3600 lb car needs JMHO

Also I'd go with a duel pattern type grind camshaft if it were me :idea:

You can get better

longrodsbc

I agree, but I have the cam new in the box, and a new set of Howards direct lube lifters, Id hate to spend more money on a new cam if this cam will work ok, Has anyone ran this cam?

I dont want a snail, so Im open to suggestions..



thanks, longrodsbc

yes, it will work fine

It should work, although i'd recommend going with a roller cam vs a solid lifter cam.

I ran a roller cam that was bigger than that (.710i/680e, 278/276 duration @.050 lift) in a 488 ci bbc for several years with some ported iron rectangular port heads and it worked just fine. Was able to run a consistant 9.80 in a 3300 lb car.

Well,
I am going to have to disagree with my buddy Tom a little bit here.

It should work Ok but you will not have much vacuum if you have power brakes. Your bottom end accelleration will suck and throttle response at low speeds will suck.

I think that with a clutch and a 4 speed it would work a lot better than with an automatic.

To my way of thinking the lift is too low for the duration it is showing. Also did you notice that the gross lift is with rockers of 1.75? I think that it would really like some 1.90 rockers on the intake but those would have to be special made.

Did you notice the cam is recommended for DRAG, not street. That is becuase of the huge overlap.

With the large duration on the short LSA and the huge overlap it will lope like an old John Dear Tractor. That thing will probably still be loping while driving down the street below 3,500 rpm.

Like I said. I think it will work but will be a bear to drive unless you have low gears, big convertor.

I also doubt that your 1972 Chevelle will be weighing as low as 3,600 lbs. Those things only get lighter when they are gutted.

Will it work? - Yes.
Are there much better cams for it? - Tons.
Would I use it if I had to? - Yes. By installing it very advanced.

Will it work in a low compression engine for street driving - NO.
Will it work in a high compression engine for street driving ? - Much better.

Does it cost mure to replace it or use it? - More to use it.

Note;
The previous that is written is only the opinion of one man.

Ed[/quote]opinion of two men i have to agree with ed. i would advance the cam time by 4degrees aleast to give you any bottom end.
