My gut tells me it is. I got a truck sitting outside with 4.56s and 37s. Doesn't run. Would really like to drive it and stay out of OD and see what it feels like. Quick math says that it is effectivly like 3.50 gears with 29s. So pretty much stock gearing with stock tires, but you need to factor in the extra drag the added frontal area and rolling resistance. Think stock Bronco towing a small trailer all the time.
The engine may be built to where a 2500 stall would be a good match. But the gearing and tire size tells me it isn't.
