Hey i was looking into selling my 5.0 and getting a mach 1 i was wondering under boost if anyone new the limitations of the block/ and does the mach 1 have the same short block as the 03 cobra??

ZW99GT

Nope. 5-spd Machs have forged cranks, but pistons and rods are GT'ish. Fun cars. They could handle 400rwhp(~8-9PSI)

Clutch_2000GT

but it is the same 4 valve motor as the cobras, just without the built botton end, so it could/should be able to handle more then the limitations of the 2 valve motor which is around 425 (safely)

ok, so to upgrade all i would have to do is get forged internals and basically i would have a cobra engine minus the supercharger

ZW99GT

Umm nope. It doesnt have a built bottom end. It IS NOT the same engine as the cobra. So, try again.

The rods will not hold any more than a GT

Clutch_2000GT

can you not comprehend what your reading, I didnt say it was the same motor, in fact I said that it was NOT built up, so why dont you try again punk

ZW99GT

If you forge the bottom end, you have a forged Mach motor. Nothing more, nothing less. Theres nothing Cobra about it.

ALL SVT engines are HAND BUILT. Mach is not.

sorry dont know to much about the modular engines, all ive ever known is pushrod so its a bit of a change to me

ZW99GT

But it is NOT the same 4 valve engine as the Cobras. This has been beaten to death, still idiots will tell you they are the same.

AGAIN SVT ENGINES ARE HAND BUILT AND ARE NOT COMPARABLE TO ANY OTHER ENGINE

kweb, Mach's are Badass, and a nice step up from the GT. They are rare, and respond very well to mods.
