Note: The HTL series of camshafts give the maximum performance available with a flat tappet camshaft and .904" diameter lifter. When used with 1.6:1 ratio rockers they will achieve lift rates and performance of a roller tappet camshaft. Also similar to a roller camshaft, the HTL cams give very wide, flat power curves, but piston to valve clearances must be checked closely.

Caution: Minimum piston-to-valve clearance is .060" intake and .100" exhaust. If your clearance is not adequate, we have tooling to cut deeper valve reliefs.
Check our tooling section or call us.
 

Maximum lift with stock guide height is 0.450", more lift requires shortening the valve guides.

Spring Warning: Our camshafts are not comparable to other manufacturers and require special valve spring pressures to operate and live satisfactorily. We suggest that you only use our springs, most other springs will not work properly and may cause severe damage.
