I have a 1986 2wd that had a 2.8 TBI and I have 89 4.3 TBI that I have installed into the truck.

I have a turbo 350 trans.

My question is the distributor plug is different from the 4.3. I have a plug that came from a 92 4.3. Should I wire the plug ABCD matching or the wire color matching.

Engine came out of 89 S-10 4x4 Blazer. The exhaust manifold on passenger side curves toward frame and I am unable to install y pipe. Do I need a manifold from a 2wd. Are both manifold different from 2wd to 4wd.

Is there a part number on manifold I should look for.

Thanks in Advance
