just a question

ok my question is this i have an 04 gt and i want to switch from 2v heads to 3v heads is it a direct bolt on operation or do i need to do some major work to make it work ?

I don't think it is a direct swap....I'm more knowledgeable folks will chime in a bout this.

You will need a new timing cover, imrc deletes, intake manifold, ect. It is doable but if you are going through the hassle you are better off with the 4v swap as the parts are more plentiful and usually cheaper.

If you are looking for more power look into the new Trick Flow 2v twisted wedges as they easily outflow the 3v heads. If you port them you can pretty much say goodbye to any 3v GT similarly modded.

^^^ Those heads are pretty expensive though, right?

 

[BoostedStg02]

why go 3v when you could go 4v for cheaper??

I haven't heard of anybody doing a head swap just a complete engine swap.

I think the Computer & wiring harness will also be a lot of work.

THere was an article in a Mustang rag this month about swapping a 4V into a 2V Bullit, its do able but also a lot of work, amny little things need to be retrofitted and massaged.

Def a lot of work, I looked into the project for my 04 GT and you have to deal with intake manifold, timing covers, valve covers, computer, wiring, plus the heads them selves and all the labor. Ported aftermarker 2v heads are def cheaper and easier in the long run.

patriot makes nice heads for the 2v... if your going to spend big money why not get a 32v 5.4 ?

not worth it.........save up for boost. The labor on a S/C setup is a fraction of what it is to do heads and cams

Those heads are 1995.00. It would be cheaper getting those than to source out everything needed for a 4v swap. The heads flow pretty much better than any out of the box 4v anyways.

Stop living in the past, the 2v with those heads will see a resurgence in builds both N/A and FI. 300cfm is not going to be impossible.

Remember a PI head flows 166cfm and these twisted wedge heads flow 240cfm unported.

The only limiter on the cars now will be the lack of cubic inches.
