Don't kow how I missed this thread..

This spring I had my Pantera on the dyno to tune the carburetor, and we kept working at it until the mixture was correct for each test scenario. The general trend was to make things leaner. This is the result:

Holley 4778-2 700 cfm double pumper

Primary: jet 65, squirter .028, power valve 6.5, cam 466 (black)
Secondary: jet 76, squirter .028, power valve n/a, cam 466 (black) hole #2

Matching numbers block, 4v heads, Edelbrock manifold, upgraded valve train.

I'm now pleased with the throttle response, and the car no longer smells of gasoline all the time. We also found a few horsepower, with the final result being 335 rwhp. If what I read on another thread here is correct (20% loss through the drivetrain), this is approximately 415 bhp at the flywheel.

It could probably still be made better, but I'm not going to bother, because I'm in on the group buy for the quad Weber IDF manifolds. I'm looking forward to having those on the car.
