Engine swap help

I have a 1993 wrangler 2.5L 4cyl and a friend of mine has a 350 chev engine that he is willing to give me. His transmission is out, he said 3rd and 4th gears are shot. Can anyone give me price of what it might cost if I did the swap myself and what it might cost to pay someone to do the swap? Everything on my jeep is stock.

Go to Novak and Advance Adapters' websites and start reading. There is lots of info there. As for cost on you doing it, there is no way for us to guess that because we have no clue what you capabilities are. Paying someone else will depend on what all they have to do but let's say $2,000.00.

Thank you! I know there is no way to get an exact number. I just want an estimated price give or take $500-$1000...so that I know if I can afford to do it right now. So $2,000 is a good start for me. I have his engine and all of his wiring. As a matter of fact I have his entire truck with engine still mounted. I want to know the price estimations of doing it myself vs paying someone to do it. Including all of the conversion kits and necessities. I have been trying to do the research but if you or anyone can ballpark me I would appreciate it!

I'd guess minimum $1000 to do it yourself depending on the current motor set up and what transmission you decide to go with. I did a carbed 350 swap for around $1K a couple years ago but that was bottom-dollaring everything and there were a lot of things I was unhappy with.

Doing it right will probably cost you closer to $2K, and getting someone to do it will cost a fortune.

What sort of mechanical skills do you have? Are you a decent welder/fabricator. If not either don't start or be prepared for it to take a while, with a lot of learning happening. It's a great way to learn with a fun project, but there are a pile of 350 YJ's for sale out there mid-swap when the owner ran out of time, money, or skill.

I can knock out the TBI swaps easy enough. Just did one over X mas in a YJ in fact.
Cracks me up when folks say you need adapters etc. I have yet to buy one after quite a few swaps. Novak make excellent motor mounts though, which is the only thing I buy.
If you get a tranny that bolts to the motor, and a 231c hd transfer case, you are set.
The 350/700r4/231c hd combo is a strong, cheap and easy swap to do.
Myself, as well as plenty of others, have made threads about it all. The 4.3 is exactly the same swap as a 350 if the induction is the same.

Good points Leftlane.

TBI is definitely the way to go, and back it with a chevy tranny and t-case.

I had a 700r4 for a year that worked pretty well, now an SM465 is even better, though less user-friendly on the road.

You can also make Chevy 208 or 241 transfer cases work, but the 231 is probably the best choice.
