O'K i probably donot need my nose in this discussion, but i have been there with some engines i have set up. As far as the setup, you need 18as to 20as nozzles in the manifold, and they need to be in the lower manifold. You need to set the leak down on the barral valve at 30% for starters. Run the engine and crank the barrel valve adjustment down until it burps when you crack the throttle, increase by 1/2 turn on the linkage and it should respond without a stutter. I'm not saying it will work in every situation, but the last car i setup ran 5.80's, it was a 565" and the car a 55 chevy weighed 4100lbs..
