Chev V8 Swap?

Hi All,

My old man just bought himself a CJ8 with a Chev 350 in it! Now... let me start off by saying, the beat of the V8 has gotten to me quicker than i thought it would.

I am considering doing a 350 swap into my TJ. I currently have the 4.0L I6 in my TJ. My TJ is a 2000 model, D30 front and D44 rear. I have a Heavy Duty SYE in the rear and 2.5" OME lift with 1" BL.

Since it is a 2000 model, i believe it has the AX-15 gearbox and the NP231 transfer case.


My question is this - is a V8 swap into my TJ worth the cash and the effort? Or should i just look at perhaps modifying the I6 a little more (it has a 2.5" straight the exhaust system)?

Any input will be appreciated.

Thanks,
Will

My exhaust system does sound nice - gives the jeep a nice beat. I would say it gives more power - but i could be giving a biased opinion. I havent had it on a dyno or anythign like that.

Thanks,
Will

It's cheaper and easier to just stroke your 4.0L into a 4.6L.

modify the 4.0L will be ALOT more cheaper, but i mean - youd basicly just be average still. im swapping an ls1 into my wrangler and i dont care how much money i put into it (closing up on about 5,000 now) i am going to have a huge smile on my face everytime i drive it/think about it/see it

that is how obsessd i am with a v8- if you dont feel this way, id just stick to modifying the 4.0

I'd have to agree with you on this one...

im actually in the prosses of doing a Chevy 350 swap

im custom fabing a long arm lift for it

triangulated 3 link in the rear 4 link in the front, using 3/4 heim joints and 4130 chrome-moly tubing for the arms, should be stout.

using a built 400hp small block, turbo 350 trans and transfer case out of a k-5 blazer and custom drive shafts

total the swap its self will cost somewhere around 2 grand

then another 2 grand for 35's and all the things i need for the suspension and putting the Aussie locked 8.8 in the rear

ill start a thread when i start dropping things in, for now its all disassembly



400hp and 430 foot lbs in a TJ

and you want to talk about a flat tq curve ahahah

would would never be able to squeeze that kind of power out of a stroked 4.0 with out forced induction or running on race gas both of witch would be less reliable and more expensive then a solidly built Chevy motor

the sound is amazing and its alway nice to smoke that 350z sitting next to you haha
