Default Just a quick 4l80e Question

How much Horsepower and torque will a stock 4l80e take? I Know i could have used the "Search" but its not working.

I believe the smallest discplacement engine put in front of the 4L80E was a 5.7L. The G2500 Express vans with 4.3L's (the heviest GVW used with that engine) used the 4L65E.

I will do some independant research before arguing further on the application list of the 4L80E. I have been a GM tech for 15 years and have never seen a 4.3L paired with a 4L80E. But like I said I will do some research before I bet my life on it.
