GM’s LM7 5.3 iron block is one of the most readily available LS blocks out there at a cost around $1200 with the harness and computer and never had the cylinder deactivation on it, making it a easier swap by a small means.Just wondering which would be the best V8 swap for the TJ?
I like the L33. Its the 5.3 all Aluminum block that comes in with less weight than the pig that they call the 4.0L
That’s the one I am referring too. I’m not sure what one of those costs, but I think that would be my choice for a swap. Being able to save weight while gaining power would be a big benefit.
Care to add to the conversation?ANY THING BUT A P.O.S. CHEVY hell a wound up rubber band is even better than a chevy
I think he wouldn't recommend a SBC in a Jeep.Care to add to the conversation?
You should expect to spend anywhere from 8-10k to have someone do it for you.
Unless you're not even changing the oil on the donor engine, this seems like a very low number based on my estimates. Obviously also depends on what kind of deal you can score on the engine too (and the more risk you want to take the cheaper you can probably find one).
Bare minimum you have to factor in exhaust, gauges, transmission adapter plates, engine mounts, possible other adapters and brackets. If you want to go a little further than that, you have costs for refreshing the engine (oil, pumps, temp gauges, spark plugs, etc) and do you expect your transmission and transfer case to live? Add those in too and now you're also dealing with new skids and driveshafts.
Oh wow, seriously? I had talked with @Stinger a while back about his V8 swap, and he was telling me he spent around 10k I believe. Of course he used a V8 engine from a Chevy cargo van, and I don't think he rebuilt it before he put it in.
I have no doubt you're right though. You always end up spending more money than you think you will on larger projects like this. That's why I'm thinking I'll just do a 4.7 stroker kit on my current Rubicon. I'm thinking that it won't break the bank like a V8 swap would, but it will still give me enough more power at the wheels to make me happy.

You're running a SC, right? Double check the info on stroking the 4.0, I've seen reliability to be a mixed bag after stroking.
lol... I'm not a big Chevy fan either but no doubt it is the number one hot rodders choice. Parts, Price, After Market.... the SBC is king.ANY THING BUT A P.O.S. CHEVY
I just hate that you cant adjust fuel and air on the 4.0L factory ECU. You are kind of running blind and crossed fingers. I have seen a lot of offerings for standalone ECU’s latley. So it can be done. It would be another 2-3k if you want to do it right.Honestly tho, price out a Banks Turbo or SuperCharger before committing to the V8. If your 4.0L is still a strong engine forced induction is probably way easier.
