I have a Oldsmobile 496 Stroker and the camshaft that I purchased (Edelbrock 2152) it's too big as it hits the counterweights of the crankshaft, I want to use the factory rocker & pushrod setup and possibly use a flat tappet cam any suggestions? Or even if I have to upgrade to a roller cam is there a roller cams that I can use with the stock rockers. My setup is .060 bore 4.500 stroke the intake & heads have been heavily ported and Gasket matched, my heads are factory iron J heads & intake and exhaust Runners have been heavily ported 10.2 :1 compression ratio & for carburetor I have a Quadrajet 750 CFM and also an 800-cfm Quadrajet...

 

How in the heck can the crank counterweight contact the camshaft?

 

Do you have the timing gears and chain installed when you are checking. If not install them and recheck clearance.

 

heres another thread on that

And either carb is way too small for even a mild 496.

 

Thanks fellas I got it figured out...

 

What was it?

 

The fact that you're using "J" heads and a factory intake is really confusing me
