So tomorrow, after an exhausting 5+ year search I believe I'm finally scoring an 1988 Cutlass Supreme International 5 speed. It appears like its in decent shape and also was told it runs good. The clutch is spent though. So assuming this car is what I think it is my plan it to do a slow overhaul of the entire car. I sold my 40th GTP and My 85 Monte Carlo is pretty solid so its time for a new project. I need suggestions as to what direction to go with the car. I want to keep it an original stock looking car and if I upgrade its performance I want to keep it somewhat true to its stock form. Im thinking:

1) Rebuild stock engine and tranny. If I go this route, any suggestions?

2) Get a McLaren Turbo Grand Prix donor car(since there are many that aren't nice yet aren't terrible) and swap the motor over and have a 3.1 Turbo 5 Speed Cutlass

3) Do a 3800II SC swap. Would it fit? What would be the obvious challenges?

4) Do a 3400 v6 swap. Thinking the 60 degree v6 would be easiest swap and would net about 80 more hp than the stock 2.8


Thoughts?
