Not sure that there is an exact number, I think XR7 dave made 313rwhp on stock bottom end.

I am kinda wondering the same thing though, about what hp levels do parts in the rotating assy. start to go on an 89-93 and a 94/5 engine, how much stronger is the later model bottom end?

My guess would be about 310rwhp assuming you have the proper air/fuel and do regular maintenance.

Yea around that number seems common. I think that that point though.. youre pushing the rods and other parts hella past what ford thought they'd see.
