You'll deff put out more power than his engine, but with his supercharger you'll have to be careful w/out nos, if your running spray, congrats on a stang kill

I have seen mid 10 second 550 rwhp cars on non forged bottem ends in these cars before. Not saying his will be fine, but the right tune and such and it wont necessarily blow up...

As far as who will make more power, his car should be in the 400 rwhp range.

The stock internals on a 5.0 are all forged from the factory. Those motors love boost.

It is too hard to predict an outcome for motors that don't exist. There are simply too many variables to even make an educated guess.

Didnt the '95 come with the 4.6 liter, i know the 5.0s love boost but i know nothing about the newer engine...anyways i dont see how a stock bottom end can hold 15 psi... again though, i dont know mustangs.

The 5.0 roller motors were forged until 1993. From 1993-1995 they werent, and then the switch to the 4.6 in 1996 brought back forged internals!

I will say hard to predict, build them and have fun!
