Need some assistance in determining the torque limitations of my Tremec 3550. Currently have a Shell Valley Cobra with a Racing Performance Ford Racing 351W/370HP/360 ft lbs torque(at the flywheel) crate engine with 3:50:1 locker rear. Thinking of replacing the engine with the Roush 427R (500+ Hp & Torque). The 3550 is rated for 425 ft lbs on a 5000 lb vehicle. Can the 3550 Tremec handle the torque & hp of the 427R (Cobra's weight in low to mid 2000 lbs range)? If not should I step up to the TKO 500 or 600?
Any feedback would be greatly appreciated
