I've got over 600hp at the wheels on a 65 c10 frame. Only issues I've had was the rearend dog leggin on the trailing arms. Easy fix though. With a big 4x4 that gearbox will eat quite a bit of those ponies up before they twist your windshield out. I wouldn't worry about it. Oh I also use the original driveshaft. 2 pieces can take the abuse.
