I would like to know what physical size and stall torque converter you guys run. I have a 537 motor 264*- 270* @.050 700 lift 4.10 rear, 3700 lbs 69 firebird, t400 trans, 3500 converter. Only made one run down the 1/4 in the heat and it ran 1.52 60', 6.64 @ 105 1/8 mi and 10.37 @132 mph at the 1/4. I am ordering a new PTC converter but am unsettled on their recommendation because they started at an 8" then ended up going to a 10". I really don't want to have to pull this thing out several times. Peak torque is at 5400 rpm's, peak horsepower is at 6800 rpm's.
