350 engine swap

[88Wrangles]

clutch or clutch mechanism problems

So, I'm thinking that the old YJ ('88) could use a new engine sometime soon , and 350's are easy to get a hold of and make fit in almost anything! So my question is, how hard is it to make fit in a YJ? How difficult is it to hook the transmission under there? What other things have to be done to make it work (like as far as computers :shock: , etc)?

your best bet would be to get the driveline from a 350 equipped vehicle as well.. don't mess with adapting your transmission to it

i've swapped a 350 into my ole '88 YJ, using the stock Peugeot transmission with an AA bellhousing. Fits good enough, and I used a carb to simplify things. I'd recommend using the transmission for a 350 instead of the stock jeep transmission, it'll handle the power better and save $$ on an adapter.

If I go carborated with the 350, will I have to mess around with computer stuff at all? I really don't know anything about re-programming them or anything like that!

Nope, you get to stay away from that stupid computer crap. Ypu end up with barely any wires to worry about either. Definetely carbureted!!!

Well, you usually don't reprogram a vehicle computer if you swap engines. Instead you'd want to make sure you receive a matching Electronic control module (ECM - pre '95) or Powertrain Control Module (PCM - '96-present) with the engine. The best situation is when you can get the engine with the matching computer and sensors all together. Although you could buy a new computer for that engine year if you can't get one with the engine. :mrgreen:

Told you I didn't know anything about computers !! I'm used to old vehicles that don't have any of that stuff 8)

Nothing like FI on a 60deg. climb.....

Nothing like a $2000 MPI system frying in water

Never heard of it, and very unlikely on a factory MPFI setup. I'd take FI over carb any day.

 

[bryanjeep]

I'd beg to differ, but everyone has their own opinions.

 

[bryanjeep]

I mean with the carb vs EFI stuff. Yeah I am sure you can get the computer cheaper, but there are setups that convert carb engines to EFI for at least $2000.

 

[Bounty__Hunter]

I agree with you on price, I was questioning ever seeing one fry when it's gotten wet.

 

[White]

some are mounted under the hood (totally sealed)
No point in removing efi to install a carb. Unless the wirring is too much.
Or in this case a 350 swap.
I also haven't Seen one fry.

 

[88Wrangles]

I am definatly going with a carborator. Yes Fuel injection is nice on a hill, but I like being able to work on it easily and adjust it and all that good stuff.

What about our Ozone Layer ! Have you NO feelings...

(Note: My gas guzzling van requires a fill up everyday, 65.00 Gotta love that 6.0 Chevy !)
You only need 1 wire to keep the chevy going. Thats just to the HEI.
go with a mech fuel pump to eliminate more wires.

Hi

Thought for a split second you meant it. Too Bad

but I like being able to work on it easily and adjust it

That's just it... you *should not* need to adjust a Fuel injected system. That is why things like the idle RPMs are a fixed function of the ECU/PCM and not user adjustable... because it does it for you properly, given that you clean or replace the sensors when they need it and don't neglect the system.

Yes, the wiring *can* be a pain, but if you've got a Multimeter, a good set of schematics, and know how to read them properly, then you'll have no problems. if you attempt to work on an electrical system (which you didn't create) without a set of schematics, then it would be likely that you might not get everything wired correctly and have problems.

If you want the performance from a carb that you get with FI at angles, look into the Truck Avenger carb, I think it's by Edelbrock. That thing will keep running at angles that normal carbs only dream of.

and it lives!!

Another option for the transmission would be a T5 out of a late 80's early 90's stang.

AA make the adapter, linkage will bolt right up and will handle plenty of power

 

[Bounty__Hunter]

Why use a transmission that requires an adapter, when there's plenty of factory choices that will bolt right up? Why shell out up to $500 or more for an adapter when you don't need to?
