Chevy 350 Install

I want to install a 350 into my 86' CJ-7. Can anyone tell me what tranny is best for this? Also, what transfer case is best. Obviously, I am somewhat green in this area, but to save some green I want to try doing it myself. I live in FL, so the landscape is basically flat. I'll be using the Jeep to run around town and occasionally to get into the backwoods for camping. I have also heard that this conversion makes a jeep tougher to handle? Is this true? Maybe I should just keep the 258?

hey dude-

what kind of tranny do you have right now? depending on what you already have, you may want to stick with that.

regarding your transfer case, you should have a dana 300, which is an outstanding unit. you would definitely want to retain that with any engine swap.

Current Jeep: 2006 Unlimited Rubicon

I'm almost embarrased to say, but I don't know. I'm assuming the tranny is stock. Any advice on how to find out. Where do I look. Was there a standard model on 86's? This all new to me, so I'm learning.

You've got a few different possibilities depending on your ability, wallet and time. I recommend doing alot of research before you take any action. Hit a few Jeep Forums and do a search on "350 Swap"... "SBC Swap"... "Engine Swap"...etc. There's a ton of info out there. Basically, it's gonna depend on your vision of the finished product. A daily driver/mild wheeler won't need the power/beef as say a dedicated hardcore trail rig.

For your 86.. if it's a 5 speed it's a T5 tranny. Pretty weak behind a V8 but it could survive if you drive it sanely. Honestly, I'd look for a 350 engine/tranny combo out of a running vehicle. Second option.. a 350 mated to your current tranny with an adapter bellhousing. Also gotta remember that a 350 is gonna require cooling system upgrades and a new exhaust system.. in addition to new engine mounts...etc.

Thanks for the great advice. I'm starting to think that I should keep it simple for now and keep it stock. It is probably safe to assume that I have a 258, T5, Dana 300. I'll look for those indicators. Thanks again!

I used my stock T-176 trans and it takes a good beating. The only thing to watch for is all your oddball things: radiator hoses, belts, pwr steering pump & mounts etc...

I think you hit this on the head. The best bet is to formulate a long term plan to modify your Jeep to your needs. This includes tires, lifts, traction diffs, brake mods, ect....While you are doing this, spend some time driving your Jeep and getting to know it. You might be suprised how that list will change as you get better at wheeling and refine its application.

While we are on the subject I also need transmission recomendations. I have a 350=sm465=np205tc. I do mostly driving on the Hiqhway and need another gear. Can someone recommend a 4 or 5 speed that would bolt to the existing transfercase and bellhousing. Thanks for any help
