How much rwhp can a stock internal mach1 handle??? Also... How much rwhp can a stock internal terminator hold?

Ive never seen anyone claiming more than 720HP with an 03/04 Cobra...and minus the intake, the engine is the same I think. Same cast iron block, same fuel injection rate and same valves per cyllinder....Thats with a LOT of work though, although those motors Ive never seen anyone blow yet.

Well you could go to 2003-2004 Ford Mustang Mach 1 Owner's Club & Registry Website Its exclusive of Mach 1.

As for the block being aluminum cant withstand anything south fo 1000ho

For your question having stock internal the limit of it is pretty much 450hp being on the safe side but at the same time is a time bomb you never know when it will blow up and all depends on the use you want it and how much of a hard pedal guy you are. If its all about abusing the engine you it wont hold up hehe.

wrong, the mach 1 has an aluminum block and it doesn't have forged internals. the 5 speed mach ones came with a forged crank, and the mach 1 engine can handle about as much power as a 99-04 gt engine, which is 450 rwhp or less.

you are thinking of the 99/01 cobras. they have engines a lot like the mach 1, but the termies are completely different.
