5.3, 4l60 zj

So I bought another jeep, it has fnr long arms 36in swampers and no doors. the engine has a hole in the block that leaks oil when I am vertical, so I decided this winter would be a good time for a engine swap. I know its a swear word around here but I am a gm guy, and have completed 2 ls swaps so I am familiar with these engines, and love them. I was looking the other day for a 6.0 for my wife's street rod and found a 5.3 that is all aluminum, around 300hp, without a tune, and flex fuel, which I'm a farmer so this is cool to me. I'm thinking I will get 2 and put one in the zj as well. I've seen other guys do this on the web, but would like your thoughts on the project, and ideas on transfer case options. This zj has a 231 in it now, but I don't see a reason why the gm one wouldn't work

Wow, that's beat to h**l!

Head over to Mallcrawlin, there's at least one 5.3 swap that I know of over there. You've definitely got some reading to do.

I've used jims performance on my last 2 for the electrical end and have nothing but the best of luck with him. I contacted him on these and he will do both wiring harnesses, and tunes in the 350hp range for $1000. I can't say no.

that is a badass jeep man!

i think there are a few GM swaps in ZJs. one i know of for sure is on mallcrawlin.com. i think its called the polerbear build, just search for it and you'll find it.

5.3s are a moderately common swap in TJs. there are tons of them on pirate4x4.com

YEP it's a crawler. I don't see any problem with this swap, the first one I did was in my 97 crew cab gmc, gave jim my firewall forward harness out of the truck, and the harness for my lq9 6.0, and 4l80e harness. took him a week to get it back to me and thats about how long it took me to fab everything for the engine, in my spare time because this was during harvest. I got the harness put it on, started the truck withe the auto-start, and drove it home. These will be easier swaps as they will be 5 wire hookup, stand alone system.

That's the one that I'm positive was done, I know it's discussed pretty frequently.

Was it a good Spicer joint or a part-store joint? I'd throw in a new Spicer (5-760x, I believe) and see if you blow it up again. You can get stronger joints from CTM, but they're spendy as hell.
