99 v6 replacement engine question.

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.

Might be the wrong place to ask, but what would be required to swap in a carbureted 302/351 into my 1999 base model v6.. I'm sure it can be done.

It's a t5 trans so it will bolt up.
Just a return line for fuel and an MSD box maybe?

Just trying to weigh all my options..

Ok. Did they post it on a tread? Or do you know there name? It's just an idea I'm kicking around. No set plans yet. Looking to see how difficult this swap would be.

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.
