Due to many and varied engine combinations, Speedway Motors offers no warranty on camshaft and or lifters for either performance, vacuum or longevity.

This cam will work fine with a stock converter. 12-676-4 may work with a stock converter but it is best with a 2000 stall. Both of these are solid lifter camshafts.
