1 4cyl stang+$4,000- WHAT TO DO?

[nosfed]

I have a 92 4 banger, and will have just over $4,000 to do an efi V8 conversion. I know some of you have done the swap, so please help. I'm not afraid of this project at all, but I do want some specific feedback.

First, I will be running a set of ported TW heads, due to the fact that I can get them for $800 from a buddy. I don't think I can do a 351 with this amount of money, so It's going to be a 302, unless somebody can help there. I am planning on the Holley intake, I have a T-5Z, and an 8.8 with 4.56 gears It will have mac longtubes, no cats, and mac catback. It will also have a 70mm tb. I will be spraying it, but I'm not sure how big.

*What gear should I run?
*What size cam? I don't care about emmissions, and mileage is a moderate concern
*What pistons?(must be reasonably priced and I'm thinking cheap forged, or good hypers. I really don't think want a set of heavy *** slugs swinging around, so I'm leaning away from forged)
*do you have any warnings about wiring harnesses? I will definately get a mass air/manual setup.
*will the 4cyl ds work?
*will sn95 seats bolt in?
*how much is a power door in good shape worth?I need a pass door, thanks to some jerk.
*can I use Chevy RR on the TW heads?Since they are stud mount, it shouldnt be a problem?

Any other suggestions?

So far, with the heads, exhaust, trans setup, five lug conversion, and rear end, I've taken up $1,800. That leaves jsut 2,200 to do the rest of the conversion. I'm planning on buying as much stuff used as possible. My budget isnt FIRM at $4,000, but its not that flexible either.
