YACT: can the DOHC head from Cobra swap to any 'Stang GT?

[andylawcc]

this spawned from another thread about displacement...


anyway, correct if I am wrong, the Cobra 4.6 is basically a Mustang GT 4.6L with DOHC plus a supercharger. and the Mach 1 is just the Cobra without the supercharger.

if so, my question is can the DOHC head from the Mach1 and Cobra be transplanted to a GT? (if it gets too technically complicated, forget explaining the detail, I am just curious would it be a relatively simple swap)

bleh I'm wrong, was thinking of something different

And AFAIK, no would be the answer - SOHC is 16v, DOHC is 32v.

What does the 16v vs. 32v have to do with anything? The number of valves is a product of the heads, which is what we're talking about swapping.

From what I've seen, it can be done, but it's not worth the hassle.

and i suppose Mach1 has an aluminum block right?

All of which doesn't matter...

And yea. It's possible.

the cobra motor has a lower compression ratio as well. the mach1 is the old cobra motor. also used in the marauder.

the only 'stang I will consider is first gen fastback (1964 1/2 ?) the distant second would be the current gen. Granted that it will be a second car and I can afford one.


and from that site I saw DOHC 5.0.... so is that a swap from the current dohc 4.6 to the previous gen 5.0 or that was a stock motor from Ford.
(and whao, turbocharged Mustang... that's a rare one)
