Ok I gotcha... was going to do a ls swap but the wiring seems like a complete nightmare And trying to get the gauges to work dosen't Seem to be real easy to do with all the wiring
Think the vast amount of wisdom is to not do a 4.0 swap. Just does not make $$$ sense. Sell yours and buy a 6 cyn.
A nice V8 allows you to break even more expensive stuff. I could be wrong.
