Important Fitment Information

Designed for compatible Ford Big Block and FE engines using mechanical solid roller camshafts and .875" lifter bores.

Fitment Note: Ford FE and 429–460 engines have different lifter tie-bar clearance requirements. Verify the correct application, tie-bar length, lifter-bore dimensions, pushrod alignment, valve spring pressures, and camshaft compatibility before installation.

These lifters require mechanical valve-lash adjustment and are not intended for hydraulic roller camshafts.
