How much work is involved in putting a big block into a CJ-7? I know that Curries had a multiport injected 454 in a YJ a few years back, but how much work did it take, and would the effort be similar for a big block in a CJ? The motor I am considering is this bad boy:

Ram Jet 502

One of my concerns is clearance between the block/header and the steering shaft, there isn't much room there with the small block 304 that is already under the hood. So what issues am I going to run into while trying to stuff a big block between the fenders of my CJ-7? All comments appreciated.

Thanks,
ps3tv.

I have seen a ton of bigblock swaps in YJ's, Cj's, and even a couple of TJ's, there is info I just dont know where to send you, I just know for a fact it can be done, call advanced adapters, they can tell you exactly what, and what not to do.

Why do you need all that Hp and torque in a SWB jeep???

My bro has a 460 in his CJ. It is not all that much more work than a small block

why not?

why not?

Thats true...theres no such thing as too much torque....but i think its better to stick to Small blocks...because they are lighter, smaller and more fuel eficient....and if you dont have enough power with a Sb v8...then stroke it...get a 383 or something...

But if you still like big blocks heres a link that could help..

I'm sure it can be done. I've seen caddy 472s in CJ7s before.

BB in CJ or Wrangler

Whats up guys? I have a 88 wrangler with a 454 sm465 np205. The cool thing with the wrangler is the frame is quite abit wider than a chevy truck and the BB is almost the same length as a straight 6. I made my own m/mounts out of 3/8 plate because of the weight factor. Mepco 4x4 sells a v8 conversion radiator that is a 4 rowHD and it works really well. I also installed a 14'' electric fan just for those hot days. My jeep has plent of torque to pull a good wheely or a nice burn on the rocks!!!!! Hope a helped a little . Mike

I beg to differ.

As for your concern over the steering shaft, get one of those steering pillow blocks, and you're all set, just angle it away from the headers. Hot rodders use them all the time...

Why a Big Block?

Well, let's see... More HP, More Torque, WAY more inertia so you can run at 300-400 RPM and not kill your motor in an Auto..but most importantly

More headaches, more weight, more heat, more breakage, more cost...but it is cool.
