I decided to ditch the procharger, and goin turbo...Matt and Greg both told me that's where I would end up, should have listened!!! I think I lost the rings in #3 and now it's a mosquito fogger...

Matt Rushin is going to build me a custom turbo set up with a 76mm turbo.

So I purchased an 04 cobra longblock, and will keep the 2 valve heads, cause I don't want to go through the 4valve computer swap and crap.

Seeing that I've had problems lifting heads, and blowing out spark plugs, I may look for some used aftermarket heads...

I talked to Matt, Cody, and Jinx about putting in an auto...I don't know if I want to do that just yet, and if I did it would be manual valvebody.

As far as fuel, I think I'm going to sump the stock tank and go return with an aeromotive fuel pump(A1000 I think).

If you guys have any input or suggestions, other than buy another car, please share!!!! Let me know what you think!!!

+1 for the auto. youll be happier in the long run

There are a few things to look into when installing 2V heads on a 4V block. One of the water passages must be changed. I found this out the hard way, as have other guys. Also, you will need to use a 4V water outlet and gasket. The 2V will bolt, but the shape is different and will cause a leak. That's another thing I learned the hard way.

At the same boost levels, 4V heads will make about 75-100HP more than 2V.

The jury is still out on whether the TF 2V heads are any good or not. Several of the Lightning guys are having issues with them.

IMO, do the auto, 4V heads, and auto MACH1 ECM. Its a pretty simple swap really. Electronic VB are very nice. Put it in D and race or cruise.

Return style is the only way to go, like we talked about on the phone. Personally, I would stay away from the A1000. Its not enough pump for what this combo would be capable of. Not to mention, its not that great of a pump longevity wise.

I am willing to give a hand in anyway you need.

auto, turbo and 4v ftw

Nice! Good luck with it, can't wait to see it done!

If you're getting a cobra long block stick with the 4v stuff.

Auto is very nice with a turbo setup. Wouldn't really have it any other way. That's just me though.

And another vote for return style fuel system, although my returnless worked just fine and has for many above 800hp. If we're spending you're money though do return. lol

I had more money in my returnless setup than a return style would have cost.

Wow...I didn't know that about the heads...so I guess I need to find some 4 valve heads, I def don't need any leaks...Does it matter which heads...like the older B series heads and cams or C series...will they both work?

we can sump ur tank, and i have a a1000 forsale as well..

Both will bolt. The next issue is there isn't a good intake available for B heads. The port layout is wierd do to the fact Ford used IMRC plates on the early 4V. C heads are better in that aspect. When fully ported, the B heads do outflow Cs. There are several different heads that fall under the "C" designation. The best choice is Navigator heads. However, they will require a Sullivan intake made for Navi heads on a 4.6 block. If you use a 4.6L C head, then any Mach1 or Cobra intake will work.

Did I miss something here? The original post said he bought a 04 Cobra LONGBLOCK. So does it come with the heads or not? Any longblock I've ever talked about meant top to bottom.

jinxxxxx is the man to listen to, although all the cars he builds are slow

Well it seems as my 2v build just became a 4v build. Thanks for all the info, please keep it coming. Jinx thanks alot for all the info you shared, even on the phone when they kept cutting out. LOL!!! Anything you guys can think of please let me know.

he is til it comes time to shift

You won't regret it. I have a complete Navi engine here, that I bought just for the heads when I had my car. It didn't take me long to realize I should have gone 4V from the beginning.

so whats the motor goin in jinxxxxy?????? ????? whats it being dropped in???? what ya thinking about??? thinking about maybe dropping it in something ???? maybe a mustang ?? possibly a truck??? what you thinkin???

scoota

Yea...put it on a Vespa!

sorry ti hi-jack you thread, build sounds like it will be nice.
