New to this forum I was wondering can I get 700-800 hp from a 331? Stock block.

 

You'll need to go big turbo.

 

Not if you're talking about a late model 302 block. About 500 at the crank is the upper limit and even there its just a matter of time before it lets go. Usually will split right down the lifter valley or in the main journals.

 

The model is a 93 mustang lx with what was a stock 302 bored over to a 331 it have some decent internals coated pistons, it was sleeved as well, titanium push rods, CNC AFR heads, I can't remember the Cam specs, it will have a nitrous plate on it as well from Nos, C4 transmission, can't remember the stall on the tranny I let a transmission builder put the tranny together

 

Yeah I like forced air I would go with a 70-88 mm turbo but I want this project to be N/A
