Last month, you may recall we got a great performance boost for Jack Iafrate’s 351W engine with a set of Air Flow Research (AFR) aluminum cylinder heads. They were good for an impressive 40 hp right out of the box. The month before, a set of Hooker Super Competition headers was installed, and they were good for almost 20 horses, so already Jack’s mild 351 is up 58.5 hp with these two upgrades. His car is now making 244.2 hp at the rear wheels.

The cam we selected was a roller-conversion grind from Comp Cams, PN 35-442-8. It has a .533-inch lift at both the intake and exhaust valves, and an advertised duration in degrees of 284. Lobe separation angle is 110.0 degrees. Comp tells us this is a good cam for power above the 3,500-rpm range while still maintaining good low-end torque. It’s the middle selection of the five 351W roller-conversion cams offered in its catalog. We’ll install our cam and distributor according to the instructions, and after an overview of the installation, we’ll head out to Superior Automotive and document our situation on its dyno jet chassis dynamometer.
