Hi all, I have a 99 3.8 that's trashed. My question is what's easier and cost effective. Tear my 3.8 down, and rebuild it or swap another 3.8 in. Or swap a complete 4.2 in. Can I run a complete 4.2 without switching over too many parts? Any response will be great.
It was a long time ago and it was on a thread. Try and search it on the search bar. Can't tell you about what's more beneficial and cost efficient but in pretty sure it will be better to put a fresh motor in there
the 4.2 is probably the easiest engine swap you can do. You need the block and all the internals. The flywheel and harmonic balancer. Then use your old 3.8 heads and intake on it. It will run a little lean until you get a tune though.
