I never heard anybody do this or post about this so here it is. Would 03 mach 1 heads (or even 01 bullitt, i beleive it was 4 valve also) work on 05+ stangs? I figured they both are 4.6 and if oil and coolant guides are the same (don't know if they are) why not? Has anybody done this.

 

is this a joke post?

 

Somehow no matter which forum you go to every time you post about something you will come across at least one dic head

 

I dont think it will work....JMO

 

Don't let it get to you. Some people just don't understand that all of us don't know what they know. I thought you had a good question.

 

Try it and let us know !!!!!!!!!!!!!!!!!

 

I doubt this would work since there are so few upgraded cylinder heads to choose from for s197s...we'd have a lot more choices if there was a union between what would work for both s197 and new edge, you know? But since there's no overlap (that I have read of or seen, anyway) I'd have to say no, just pick a head+cam combo that's designed for our cars.

 

If the heads would match up, (I don't know), you would lose VVT, and the gains would be small. The 3 valve head is top shelf gear.

 

is this a joke post?



And you sir qualify for "Head Dick". What an arrogant jerk! Not everyone is a gear head! Remember this next time you are made fun of for showing ignorance on a subject. Ignorance is not a crime...stupidity should be!

NOT YOU Olvanish!

 

Isn't this the reason Ford designed the "modular" engine, so it can make inexpensive 2 valve per cylinder head engines and more expensive 4 valve per cylinder engines withe the same block? I don't know if they'd be a direct swap but a good question nonetheless.
