Somebody posted torque multiplication numbers for various stock converters a few weeks ago, but I can't find that discussion. The talk of generic vs. Pontiac specific converters got me wondering about my setup, though.
I'm using a Hurst Trophy Taker, rated 400-600 rpm over stock, 3600 lbs, 400 with 228/236 @.050. At 3500' elevation, best 60'times:
2.39 with 2.73 gears, 26x8.5 slicks
2.14 with 4.10 gears, 26x8.5 slicks
The engine and trans came out of a '70 GP (may the Black Shark rest in peace), 350 hp rating, 2.93 gears. No 60' data on the GP, but there was definitely a delay between idle and the powerband with the new cam and stock converter. I changed to the Hurst converter when I swapped the drivetrain into the new car, so I don't know how the stock converter would work with the lighter weight and the gears.
So finally, my question is, could my stock GP converter work as well as or better than the Hurst with less weight and the 4.10 gears? Or should I stay with the looser converter because of the cam? I'd like to try one of the custom units I've read about, but the price is right on these two.
