You can find GT40p on Ford Explorers imo if you want the best go trickflow on a 5.0.

Yup sadly the 94-95s just aren't as fast as the 87-93 foxbodies.... I still have to tune mine and then may possibly be faster. I am expecting it, but once I put 3:73s and the tune it should be solid and around 13.5's? Really that's is all I am looking for right now.

Stock my car runs 15s lol so I am happy with mid 13s right now. Its still faster than my LT1 6speed Formula, 14.2 is about as quick as it can go 1/4. I also don't think a 5.0 Cobra stock will do high 13s maybe the 96-98 but I dunno.

Well first off that intake and injector setup would need some serious heads and cashaft upgrading from your proposed gt anything!

What is your cuin and power goal?

That intake and inj setup on a 30?cuin will be a flop and you wont like it!



OP the difference between the 2 are one is a production mustang piece and the other is aftermarket, although you can get the cobra in a GT40 style good for mostly stock engines, the heads are the same exept for the header design to fit the exaust. they too are good for very low output engines close to stock!

You should back up and rethink what you want here before you waste any money!
