What happens here

Bennie machined the rocker arms from billet aluminum. Leonard then hand-finished and assembled them, incorporating rollers into the design. Bennie showcases both an unfinished and a finished rocker arm, explaining the need for different lengths for intake and exhaust valves due to the hemispherical engine design. The fasteners for the rocker arms are miniature titanium bolts to reduce weight.

Goal: Illustrate the creation of the specialized rocker arms

Tools and materials

valve rocker arms ? Benny turned them out, and then we made a rocker arm with a roller on it . Here's the rocker arm. This is the intake rocker arm. The intake rocker arm on the Hemi is short, unlike the exhaust rocker arm, which is longer . The gear ratio is the same, but due to the hemispherical design of the Hemi engine, the intake rocker arm is very short and the exhaust rocker arm is very long. This is how the Ford Boss 429 was designed. The mounts, these clamps—they are titanium. Did we do this just to lose weight? This is already a finished product. But this graduation rocker is an unfinished product. This is what it looked like when it came off the milling machine and I finished the job. Then I handed it over to Leonard, who polishes and reassembles it, putting in the roller, adjustment nut, and everything else. And when he finishes, it looks polished, like a trophy to be proud of. This is madness. Yes. Did you make this locknut too? Yes, the counter nut is titanium. Madly. And then the rocker arm, it's also needed. The racks
