QTY

will I need to machine the vortec heads on my blue print L31 crate motor,when running this cam? How much more TQ. & HP should I expect?

Asked by: babyboo
You should not need to machine the heads, but you will want to check the valve spring coil bind. The TQ and HP will vary widely based on the rest of your engine setup.

Is this compatible with the stock distributor gear?

Asked by: Noahofficial1999
Yes, if you are replacing a hydraulic roller camshaft.
