Approximately 220 Net. Varies slightly year by year...
150 at the rear wheels if you are lucky...
Use this link and look for the instructions on de smogging your truck if you are not required to emissions test any more. The increase in power and mileage will be noticable...

whats the torque going to be like. i bet its got to pretty gosh darn high. also, i dont think it came with smog crap so....
also, with 4.10's in the diff, with a high flow airfilter, and a bigger carb, what can i expect for gas mileage.
the thing is running like a big pile of poop at the moment and i am doin roughly 4. when i change the plugs, fix the timing(cuz its missing like mad right now) can i expect an increase to about 8-10 mpg's?
thanks

I have a 78 F-250 XLT 2wd...
I have recurved the dizzy and placed a holley 750 on the factory spread bore intake by modifying the EGR spacer plate with a carbide burr.
The engine has 100K on it and still has the original timing set and cam. I get about 10 MPG with single exhaust sounding like a street sweeper.
I don't have the time to port my own cylinder heads LOL...

i totally understand, all i have past the manifolds is two totally hollow cherry bombs. it sounds so mean, but it has a very dirty sound too it. very very throaty. plus about 4-5 ft of the pipes has been removed off the back. loud is probably the best explanation.

In 76 the 460's were pretty smogged down...
The cam was revised as was the ignition timing curve. Add to this the retarded cam timing and you can see why they were dogs.
Desmog the truck per the instructions and you will not be disappointed.
Torque net was about 400 pound feet. Mostly due to cam timing and poor ignition curve.
