Not sure but with 3.08gears, stock TC and 80E.. i bet it doesnt get out of the hole too good.

This thing is really a mover!

The torque on it is really great, it just runs out of steam around 5000, a complete fall off the mountain.

I think it is time for cam and springs.

Those numbers are similar to what I was running at 6psi on my 5.3L but my torque was no where near 467, I think it was 398ft/lbs for me. I can see the 6L doing better than mine easily!
I have no idea why she would die down after 5000rpm's what cam is in it?

.96 a/r on exhaust housing!
