hopefully not a hijack of the thread, but I'm looking at a different option: I have a straight axle 4 link suspension, so if I want to go with a 5 speed anything longer than a toploader will not work (leaves me with no rear suspension travel as the driveshaft gets too short).
Looked at G-force transmissions, they show a 600hp capable T-5: here's from their website:
G-Force Transmissions and Long Shifters
Generally, it can be assumed that with the available upgraded mainshaft, the G-Force Street 5-Speed kit will handle roughly 600 hp or 500 ft-lb. of torque in a 3300 lb. vehicle running drag radials at the track with a moderate clutch upgrade.
Anyone have any thoughts on this option? I'm running a 460, havent dyno'ed but I'm guessing somewhere close to 500hp flywheel.
