Do to recent events my 4.0 is done for so time to start looking for a new engine. I am contemplating putting a 4bt in it and know that it won't be cheap or easy but thing it would be worth it. I don't wish to put a Chevy 350 in it. I am not fond of it. I am also looking at the 5.7 hemi. Hoping for anyone's suggestions.

See the link to my build thread below. It's a 50 state CARB certified hemi conversion.

The hemi or an LS are the only ones I'd consider. Be advised.. It ain't a cheap or weekend job if you do it yourself. Time,money,planning and proper tools are mandatory.

And it was worth every penny spent 👍

Why not a stroked 4.0... I think they are a 4.7. Bolt in no fab. Minimal mods

What happened to the 4.0L? How many miles?

Golen makes a bulletproof 4.6, but you could make it anything from 4.5-4.9 really. I think ATK makes a 4.7 crate engine. When my 4.0 is done I plan on putting a Golen 4.6 in my LJ.

it had a hair under 200,000 miles. The block cracked

And I am doing this myself and know that it won't go quick I have helped on 2 other motor swaps lol so I know what I am in for!

I think a 4bt or nearly any diesel would be an awesome project. Here are some pictures from FourWheeler. Even the TDI is neat.

how did that happen?!?

My original went to 320,000 when she went TU

Sounds like a cracked piston, in the process of replacing with a used engine

The 4bt will be a nightmare....... Its the reason why so few are done.
Heavy, vibrates like crazy and heavy...

Going V8 is a smart way to get some serious power on the lighter side of weight.

a 5.3 out of a Chevy will be about as cheap as you will get and have serious power.
Or any dodge 5.2 or 5.9 from around 99 up.. the Hemi is just too dang expensive unless you find a complete wrecked donor..

I have done every type of swap known.... I will not do a 4bt...

It's a huge pain but I decided not to go with a 4bt and that it would be easier to put a 4.7 stroker that was turboed in and it should get some where in the ball park of 300 hp and 320 ft/lb torque

Good luck with getting any kind of reliability out of it..All I have ever heard is drivability issues and fighting the ECMs..A turbo will only complicate the matter.
