Call me stupid, but I can't remember what engine was in the Terminator cobras. Was it a 4v 4.6 or a 5.4?

4v 4.6

5.4 was the Cobra R.

OK cool. I could have sworn that they used the the 5.4 in a cobra prior to the GT500 and i guess i was right.

On another note, how much difference is there between the 4v in the mach and in the cobra (other than the blower of course)?

AJ06GT

The Mach 1 has the aluminum block, the Terminator the cast iron. I think they both have forged internals though... someone can back me up on that because I'm certainly not 100% on that.

machs only have a forged crank

AJ06GT

Ahh k, thanks, good to know.

JJ03MustangGT

only 5 speed machs have the forged crank.....just thought id add that in

QatarStang

Alright thanks for all the responses guys.

AJ06GT

Actually, now that you say that I did know that.

To make it a little less confusing for other people...

5 Speed Mach 1's have a forged crank, everything else is cast. Automatic Mach 1's have no forged internals. 03/04 Cobra's have complete forged internals capable of withstanding 600+HP.
