I have now updated this thing to where I'm now running the Fast 2.0, and have everything else electronic in the car you can buy (or it seems). At this point I don't know if it is even beneficial to change. Anyway I start researching then give up after I lose sight on what I want to do.
My goal is I want at least 500-550 rwhp N/A (either build a 427 SBC expensive, and keep everything front accessories). or Build a LS type engine to meet what I want, and use what I can from what I have.
So here it is.
1. I'm running a 1200HP rated 2004R can I keep this tranny with the conversion.
2. I have the Fast 2.0 (so is the what I need to run the engine?? If so what else do I need for the LS egine (is the a ecu/harness unique to the engine). This is where I have been getting lost. How much wiring comes with the engine or is it just a engine harness that will connect to the FAST 2.0. I spent 2300 on the Fast 2.0
3. I have the vintage A/C, I can still use the compressor I'm currently running?
4. Does the LS have a special type PS box I have to use (in other words I can't use my current SBC one correct, which runs my PS, and hydroboost).
5. If I change to a LS and I can keep my 2004r, will the tranny move forward or backwards or will the engine bolt up without having to move the tranny forward or back?
6. Fuel system I'm good. I have the aeromotive stealth Tank installed already with a feed line to the front (regulator), and a return line.
7. I have a MSD6AL that is controlled by the Fast 2.0, which I think I would need to upgrade to one that can control the coil packs? Another area that I get lost.
8. I have O2 sensors in both exhaust now, one goes to the Fast 2.0, the other is monitored by my nitrous system.
My thinking is and I don't really know, is I might only need to get a LS engine, headers, engine mounts, tranny adapter if possible, oil pan, front drive assembly that I would be happy with (want the A/c on the passenger side, down low if possible), radiator (I have a aluminum one know). Again so confused/lost at this point. I can do all the work (hopefully).
At this point I'm thinking the LS route only due to the fact it is such a easy power plant, plus you get even fuel distribution, individual coil packs per cylinder, just seems right.
I'm I really gaining much from where I'm currently at?
Here is my current engine

Yes you can with a flexplate adapter and correct converter.
2. I have the Fast 2.0 (so is the what I need to run the engine?? If so what else do I need for the LS egine (is the a ecu/harness unique to the engine). This is where I have been getting lost.

I believe you can with the right intake and ignition upgrade.
3. I have the vintage A/C, I can still use the compressor I'm currently running?
Yes, with the right drive system. We run Wegner automotive on all of our build and it uses the SD7 comp.
4. Does the LS have a special type PS box I have to use (in other words I can't use my current SBC one correct, which runs my PS, and hydroboost).
You can use the same steering box and hydroboost. You get a new pump with the accesory drive set up.
5. If I change to a LS and I can keep my 2004r, will the tranny move forward or backwards or will the engine bolt up without having to move the tranny forward or back?
Same location with the right engine adapter plates. Trans stays put.
6. Fuel system I'm good. I have the aeromotive stealth Tank installed already with a feed line to the front (regulator), and a return line.
As long as you can regulate to 58 psi.
7. I have a MSD6AL that is controlled by the Fast 2.0, which I think I would need to upgrade to one that can control the coil packs? Another area that I get lost.
You may need a new ignition controller to utilize the cam and crank sensors. You can call MSD tech. They are very helpful.
8. I have O2 sensors in both exhaust now, one goes to the Fast 2.0, the other is monitored by my nitrous system.
Again should be fine if you are running the correct set up for a carb manifold LS engine.
