With the power band of the engine being from about 1,000-5,600rpm what would be the best carb to go with? I am probably looking for a vacuum setup and I would rather have a holley for tuning preferences but if you know a far better carb please tell.
LeAnne's answer is pretty good....a carb sizing chart shows it should have around 525 CFM at 90 percent volumetric efficiency but 600 CFM would be close enough. I'd prefer a spread-bore carb for better low-end throttle response and fuel economy, vacuum secondaries and electric choke. The problem with spread-bore's is you have to commit to a manifold for it also. Holleys are pretty good for tuning or pickup a cheap Rochester set-up to fiddle with....parts can be had through a GM dealer.
