NEVER put a 750 on a 318........
I had a Holley 800 DP on a 289, 4 speed, with 4.10 geared 8.75 Mopar rear,
Super Stock springs with pinion snubber. Don't know any hp or torque but I could let the clutch out just above idle and just start rolling, then stomp it to the floor and it would pull like a 440. Then at about 6500 rpm, those L60s would bust loose. Ride it out until it stopped spinning, at 8000rpm yank 2nd and repeat, then chirp the tires hard in 3rd. I hung out with mostly 440 Mopar a-body drag racers and even they were impressed.
