I like the breather caps for the head covers you got going on. Hows the pressure? Compression ratio? Pinned or welded rear end?
9 to 1 compression with 12 lbs. of boost in street tune. Pulley change made 15+.
Rear end had an Auburn Pro-Posi unit. Strange engineering axles and disc brakes. Hotchkiss suspension mods front and rear. Handled like a slot car and ran like a scalded dog.
535 HP to the rear wheels in street tune on pump gas. Never dyno-ed at high boost on Cam-2 blue iio octane racing gas.
