Intake CL for ZL-1 cam

[Peter426]

I can't answer your question specifically but do know when you advance a camshaft you increase bottom end and lose some top end and vice versa when you retard a camshaft. Always keep in mind (and don't forget to check) valve-to-piston clearance after doing so. I forget if the intake or exhaust valve-to-piston clearance is decreased when you advance the camshaft and conversely if you retard a camshaft.

The optimal (and easier) method in my opinion would be to do this experimentation on a dyno vs. at the drag strip.

Good luck.
