94 wrangler, soft top, 5 speed manual, 2.5L in it. I happen to have a chevy suburban next to it, from either 72 or 77, I forget which...I believe however, it's 77. Which is sad news, because that means the smallest engine was the 350...is there ANY chance the 350 could fit in it without MAJOR modifications? (Such as having the extend the engine area) Some cutting is fine.

Click here for a primer on what's involved.

Keep in mind if it's worth doing, it's worth doing right. It's expensive, and if done right, your YJ will be worth more. If not done right, your YJ will be worthless.

Three to four thousand dollars would be the absolute minimum I would budget, and realistically, probably six to seven thousand.

Turns out it's apparently a 1972, with the California Package, which was rather rare..400. I'm not seeing a 400 fitting in it without some pretty serious stuff-Besides, with a 400, It might be better to put it in the body from, say, a nova, and have a little fun with it...

The '70's 400 is a small block. So, it's the same size as a 350. But, the 400 small block is well documented as being a POS. Some racer guys like them, but for the street and longevity, it was a bad motor.

I heard the heads have very thin water jackets and tend to over heat alot...if you want reliability then a properly built 350 will last a lifetime.

That's right. And the block has siamesed cylinders also which led to hot spots and cracked blocks.

If you got it. use it. build a 350 if thats what you want but you can get started with what is available to you. I ran a 400 in a 76 K5 blazer bored 60 over and camed and loved it. never got hot. I had a 70 Nova SS that had been wrecked and had a different front end stuck on it. I built the 400 to run 10 sec 1/4 miles with NOS. Never heated or cracked. they do have some problems but hey so can that 4 banger you have now.
