This is just over 700HP with a roller cam in the 700 lift range. and IMO , it's to much cam or not enough gear( it's a 4.10 Dana)

It wants RPM'S




Wow, that is a lot of cam and gear for the street.

Reasonable to me ended up being 493 inch motor with a mild .550 lift hydraulic cam'd, mechanical carb'd motor putting out a very streetable, very low-maintenance 684 hp/682 ft lbs of torque at 5500 rpm; through a 4 speed and 3.54 geared Dana getting 9 city and 12+ highway at 70mph.

Should do a bit better on the highway with Jamie's 5-speed. I can't imagine running lower gears in it, with over 500 ft lbs of torque at 2000 rpm it just doesn't need it.
