Any Bay Area folks out there have a used set of Superformance side pipes they could let me modify for use on the dyno?
I just did some preliminary dyno work on the all iron 483ci tunnel port I built for Gene G.
With small, economy 1-3/4 truck headers and a carb problem that is only allowing about 2/3 secondary throttle blade opening on both carbs, the engine made 565 hp and 565 lbs torque.
The hp was made at only 6000 rpm.
The pulls were made on pump gas and 36 deg timing.
If I can find a good set of headers and get the damn secondaries open all the way it should make well over 600 hp.
Thanks,
