4L60E - hp and torque rating?
 

Does anybody have the max. hp and torque ratings for the 4L60E through the years?

Trying to figure that one for my build.

4L60-E

The 4L60-E is rated to handle up to 360 ft·lbf (488 N·m) of torque. It weighs 133 pounds without transmission fluid.


4L65-E

An updated 4L60-E, the 4L65-E (RPO M32), was phased in the 2001 model year when coupled behind the 6.0 Vortec. Five-pinion front and rear planetaries, along with an additional 3/4 clutch allowing 7 clutches in the input housing and induction hardened input shaft assembly, were improved to withstand up to 380 ft·lbs (515 N·m) of torque.

Thanks,

Nice - it will be enough then for my mild build. I'll for sure not be over 300 ft-lbf (400 Nm) on the torque rating. So I will have it rebuilt as I have no time to dig into that as well.
