I have an inline 6 4.0L High output in my Cherokee at the moment. I am wanting to put a crazy big engine in there but I am not sure what to look for. I have looked at a couple V8 engines but I am not sure. I just want her to roar when I put my foot down and have the power to back it up. Want to be pushing well over 350 hp. Can anybody give me some advice. Thank you.

 

drop a 350 in her.. you will have to do some chopping if you wana go bigger then a 350

 

I have a 4.3L in mine and I can tell you it is a lot of work. You will need to put the Chevy tranny in too. Mine is a 4L60E. I don't think the tunnel is big enough for a 4L80. One of the biggest problems though is that the XJ is not wide enough between the frame for it to breath with a small block. I've been fighting cooling problems and I have a Griffin radiator. I think I have it now though. But honestly, 500 hp might be a little much for the unibody.

 

Pics!!!! I think alot of readers would like to see your play toy.

 

LS1........

 

Just make a 4.7liter stroker..

 

I've thought alot about this.....You could always go with a 300I6 ford, bore it over, there is a little aftermarket support for it, it would definitely be unique! You could put a dodge smallblock in it, like 318, that would be unique.......

You could go chevy if you wanna be like everyone else, its cheap and easy to find, I think its a cop out and there is much better stuff for a 5.0 ford and its a very light and there is a TON of aftermarket stuff to go any way you want. I would couple this with a ford 5speed out of an old mustang, or even better instead of a 5.0 do a 289, same block as the 5.0 ford just a tighter crank so you can really rev that one up super fast. I've seen a couple of CJ's with a 289 in them that were BAD ***.

I'm eventually gonna go big block in mine but thats way down the road. whatever anyone tells you, there is one rule as a gearhead. THERE IS NO REPLACEMENT FOR DISPLACEMENT!

Whatever you do there isn't a kit, your gonna have to fab and work it all out yourself. I'd do a ford windsor engine, tons of aftermarket, the power is not at cheap as chevy but is definitely more reliable. Do a windsor family engine, they go from 260, 289, 302 (5.0), and 351. and most of the blocks and parts are swapable (except for the 351).

Chevy Sucks...........

 

OK, here it is. As you can see, it is busy under there.
