I have a 650 Demon DP on a stock displacement 351 (actually a 357 w/ 4.030 bore). This thing works terrific, and by far and away better than the Holley it replaced. You may find that the 650 you now have does everything you want it to (fatter tq curve) up to around 5500RPM. If you need the 5500 - 6500 RPM power, go for the 750.
