Earlier this spring we got the opportunity to swap in a solid roller camshaft in a 406ci SBC Drag Truck engine. The engine previously had a solid flat tappet camshaft. With similar camshaft specs we were able to gain 50HP average across the RPM range. Final numbers were 581HP @ 6300RPM & 546TQ @ 4800RPM
Engine specs are single plane intake, Strike Force Ported Aluminum heads, solid roller, 10.5:1 compression on pump gas
