I just installed the ram jet engine with a 700r4 transmission in a 91 camaro rs and it fit perfectly except that I had taken a y pipe from a trans am and it didnt fit.

I installed the exhaust manifolds from an 89 caprice and those fit for the most part. None of the front accessories fit from a 89 caprice 305. Does anyone know what car I can definitely take all of the parts from and it would work? I would like to put headers in it and I saw some on ebay for a chevy truck that looks like its set up at the same angle I need heres that link:

Im also wondering about the electronic connections on the transmission. Do I have to keep those connected with the main computer? Any other electrical gremlins that I should be aware of? I already changed the fuel pump to supply more fuel and now have to adapt the gas line fittings to intall the lines.
We figured out that we just needed to grind off a part of the bracket to get the power steering pump side on and then everything else went smoothly so we're getting closer to starting this thing.
I have to connect a B positive connection to the ignition ...does anyone know a good place for it?
Any help would be greatly appreciated.
Thanks!
