I’ve recently acquired a 82 cutlass 4 door with no engine no transmission. Used to have a V6 I believe. It was parked for 20+ years so body and interior is in awesome condition. I’ve asked around and my mechanic friend suggested an Lm7 swap with 4l60e transmission but I see a lot are opting for Ls swap. Which is easier Fit and cheaper Route? Or which would you suggest?
