I have almost everything I need to swap out my 2.5/AX5 combo to a 350/T350. All I need to start the swap is the crossmember for the frame and the bigger radiator. I have the 350, turbo 350 trans, Advaced Adapters adapter plate to bolt my NP231 to the T350, wiring harness, ECU, injection kit to replace the TB on the SBC and a Ford 9" rear end (that will need to be regeared most likelly).
I want my 90 YJ to be dependable to drive across country with no worries, have the power to wheel just about anywhere I go yet still have the ability to maintain speed on the interstate.
What are the pro's and con's between swapping to what I already have in hand or shifting gears, selling what I have and getting a 4.0 HO and an AX15? I know it's just about the same amount of work for either one, so I'd like to hear from you guys that have done each or both and see what your thoughts and opinions are.
Treat every situation like a dog, if you can't eat it or play with it, pee on it and walk away.
As a side note, if you had a 91-95, then I'd generally recommend the 4.0/AX15, since the wiring changes and most of the swap is very straightforward. And it's more "stock". But even for this hypothetical, if you have the SBC, then drop it in!
Also, it would be helpful if you would fill out your profile, so we can see axles, tire size, gears, etc.
1995 YJ, 4.0L, AX15, 3" susp lift; Lock Right in Dana 30; 8.8 w/ARB; Flat Tummy Tuck, 1" Daystar BL; 1" MORE MML; 35" MT/r Tires;
Sell the 9" Ford and buy a 8.8 Ford with the gears you need, it's about as strong and the 9" may sell for more.
The 4.0 weighs about the same as the Chevy and can make more power, fuel MPG about the same, Low End TQ is about the same.
