I know this is against the logic but I did a back to back test at the track with a 750 double pumper vs a 7320 1150 dominator, on a stock bottom end, set up for 10 to 1 440 with a .509 hydralic and 906 heads, and m1 single plane. I even used a 2 inch spacer with both and the 1150 60 footed and mph the best. I still took it off though because I couldn't bring myself to have a dominator on a 11.40-11.50 car
