how much power can you safely put into a stock 03 mach 1?? are they the same as the cobra motors?? or do they have the crappy rods and pistons like the gt's???
how much can a stock mach 1 take????

i know that the 5-speed has a better crankshaft than the automatic i believe it's te same as the GT. The piston and rods will have to be replaced for a FI set up and the C/R lowered
so with a stock bottom end the power shouldnt be more than 400 rwhp??? any reason that the 5 speed has a better crank??

well 400hp will be easily reached with a 4V but a set of 4.10 gears, VT cams, and LT's with full exhaust and taht car will be freaking fast 
The 5 speed has a higher rev limit then the auto...thats why it has the forged 8 bolt crank compared to the auto's cast six bolt. All the machs have the same crappy pistons/rods as gt's.SaleenGT2001 said:

Too add to this... the stock crank in the GT isn't usually the weak link, it's good for 500rwhp (i think?), it's the rods and pistons (most say 400rwhp).
these horsepower numbers are just guidelines. many many factors play into what can handle what. is it FI or N/A what type of FI if it is. it has to do more with cylinder presure than horsepower it's self.
to answer your question. NO the stock mach 1 can not handle the power as a 03-04 cobra motor. the cobra motor has forged pistons and rods and a lower compression ratio.

while we're on the subject should i limit myself to 400 rwhp on my 01 gt when i put on my KB or should i let it go to say 415 if it can do so?
