I didn't have it on a track yet, so time slips are not available, but my 440 in a 383 block (438 cu inches) was a 9.5:1 unported 906s edelbrock 850 carb w/electric choke, and a comp XE275HL cam, TKO-600 and 3.21s with 28.5" tires, and it would roast the tires in first gear from a 20 mph roll...no idea what it would run in the quarter though--but with that much torque, some sticky tires, I'm sure it could have pulled off a low 13 second 1/4 mile (it's a 4200 lb truck!)

now it's a 4.56 gear'd rear, aluminum eddy heads, holley 750HP carb, and 505hp at the crank, and I HOPE it's a 12 second truck--gotta get it track legal first though--drive shaft loops, etc.
