1977 Ford Truck, Originaly was a 351 MODIFIED (Came from the factory like that), overhauled, bored out, longer pistion rods (if not, the stroke was made longer for more power, one of the two), racing heads and racing pistons, new crankshaft, better camshaft. It had dual exhausts, better spark plugs, high flow cat converters, and some kind of special sleeve or something in the combustion chamber area (dont know what they mean). It also had a good air filter, and a few other mods.
So, about how much Hp (and/or torque) are we talking about here?
It ran on Gasoline.

351/400 M is a good motor for a short period of time, and that would be under stock specs only. The heads, are they aluminum? What is the intake and exhaust size? The cam what is the lift and duration? The intake and carb what size CFM. The exhaust, header and muffler or straight dump?
Factory HP is 185/ 215ft lbs of torque. I love fords, but I have never heard of anyone building up the modified. Cleavland and Windsor yes! Check the casting on the side below the exhaust manifold and the numbers on the bell.

racing heads and pistons hummm are they 13:1 or 12:1 how big are the valves ? whats the lift on the cam does it match up with the rest . The stroke only changes low or top end performance or you rpms. Id say 350- 400 depends on a whole lot that im not seeing here just a guess thats all it can be
