I used an 800 Spread-Bore Double Pumper for both the 400 and 455 applications. The response at low rpm was phenomenal! My 400 in the GTO, a 4th-gear punch at 55-mph, about 2550-rpm, and the front end would immediately pick up and stay up for as long you had room in your shorts. That was a high-gear punch with a 3.55 rear!
