Could a Comp Cams Thumpr Cam(PN 12-600-4) with .479/.465 lift run in a stock SBC 350(1.94/1.50 valves) 76cc chambers with 2:56 gears and 350 trans?

not with stock heads way to much lift

Yeah right,,,,,,,,,,,,,stock GM heads and springs will go to a .500 lift on a hydralic camshafts easily..

The 80's called and want their 2.56 rear gearing back! ;) J/K... 8) Any stall TC? It should be compatible, but will be a dog at first. You may not get the RPM's that you want because of the stock valve train. :-k

I thought stock spring could handle maybe .470 or .480. idk Whatever the case. Comp Cams says it will run fine with a stock converter but will be better with at least a 2000 stall. My only concern is the springs.

A stock spring will handle up to a .500 lift hydralic camshaft with no worry of coil bind.. I'd look at a little B&M or TCI saturday nite special converter in the range of 2000-2500.....

Cool. Thanx for the heads up if you will. Do you have any vids with it idling?
