2.8 engine mount shells on the crossmember, JTR motor mounts, Hedman or Sanderson shorty headers, Mid 80's Corvette radiator or the Be Cool or Similar ones work well. For an auto, there isn't much special to do. If you have AC it is recommended you cut an area out and box it in to clear the valve cover and make removal of the valve cover easier.

The 2.8 mounts are needed for the V8. All the adapters from www.jagsthatrun.com or www.advanceadapters.com do is move the mounting pount forward in the engine bay.

With a 700r4, you should be able to use the stock crossmember, it just needs to be moved back a hole or two. There are extra holes in the frame. Driveshaft should be OK too. With a TH350 it is a little short.

Mine was an 89 2.5 / 5 Speed. It is now a 4 bolt 350, with a TH350.

The 2.8 mounts are mounted on the frame. The adapters mount to them, and then the motor is mounted to the adapter. The holes on the adapters are usually slotted so you can move the motor an inch or so forward or backward depending on rad/fan choice.

It is rather simple, the only real mod I needed to do was to slot the holes where the steering column goes through the firewall and move it about an inch. Interestingly enough this straightens the steering wheel. Look at your steering wheel compared to your seat, or at a right angle to the truck. It is in crooked from the factory.

You should look at something 87 and up. The pre-87 700r4's were weak.
2. corvette or becool rad

3. computer and what wiring will i need?
If you plan to use the complete TPI system, then you will need the computer and wiring harness from the Camaro.
Other than that I don't really know, didn't go that route.
4. advance adapters motor mounts .. and 2.8 mounts unless the advance ones bolt up to my 2.5 ones
You need the 2.8 ones. The 2.5 ones are quite a bit different.
5. and everything else will go together right crossmember for trans, driveshaft shuold be ok ??
Should be ok.
6. and that $30 book from jtr

You will need some sort of fan, whether it is electric or not. The factory fan might not fit, and likely won't flow enough air.

You'll also need a shifter, unless you plan to use the one out of the Camaro.
