Engine swap

Hi all,
I'm a newbe here so if you can please forgive if I ask repeated questions. I'm looking to swap out my 6 cylinder to a 283 v8 or 350 v8. The jeep is all stock. Besides the engine what else will I need? Also does anybody have a ball park of what this is going to cost me after I purchase the engine? I found a 350 with 800 miles on it for $600.
Thanks again and this is an awesome site. Looking forward to the inputs

I'm in the middle of swapping a 350 into my '98 TJ, so I can tell you what I've run into so far.

You'll need the engine, obviously. I'm rebuilding one from an '82 pickup that I got for $200. We've sunk about $1500 into it so far and will probably add another $500, but by the end we'll have a custom built Vortec monster. If the one you've found is running well you could put it straight in, or do a quick and dirty overhaul to make it run like new and squeeze a little extra torque out of it. If you don't have the time/ability to rebuild, you can get a decent new crate engine for anywhere from $1500 to $5000 depending on what you want and are willing to spend.

I'm swapping out the 2.5L 4 cylinder from my Jeep, so we'll be replacing the flimsy stock transmission with one capable of handling the power being added. Check www.novak-adapt.com ! They have a host of rebuilt transmissions for sale along with adapter plates to bolt any transmission to any engine and any Jeep transfer case. They also make engine mounts for putting a Chevy small block into a Jeep, so you'll need to get those and have them welded in.

Good luck with the swap!

Yes definitely look at Novak for bits and pieces to help with the swap. I'm using them for engine mounts and a few other parts for my 5.2 V8 swap.

If you are not going to rebuild the engine you are looking in the $3k and up range. I have over 3 in my swap with paying $500 for the engine but i already had the Trans and tcase. Also are u going to be doing the work yourself? It is pretty time consuming
