installing a 440 mopar in a cj7

I'm thinking about replacing my 304 with a 440 in my cj7. Anybody know anything about this? What will it take, and how involved. I already put a chevy 350 in my wife's jeep. Is it about the same.
Thanks
Todd

Too heavy in my opinion. A 5.0L would be a better choice.

Re: installing a 440 mopar in a cj7

The 440 is one BIG motor...besides weight, I think you are going to have fit issues...especially up around the front for the radiator. I also suspect that you will have major issues with exhaust. I don't know of any V8's that let you do dual exhaust down both sides....just not enough room on the side of the xfer case....unless you go low...which then creates ground clearance issues should you plan on doing any real off-roading.

Yea, I have to agree with the 5.0 or SBC route....it's proven....

Re: installing a 440 mopar in a cj7

I saw a wrangler with a 440. Didnt really take any notice of how it was in there. But it was in there. Anything can be done. What matters is how much you want to spend and how long can you have the jeep down.

Dual exhaust shouldnt really be a big problem. The factory v8 exhaust came down the drivers side. I ran mine down the passenger side. Its tight but its in there. Now for the 440, custom headers would probably have to be built. Somewhere on this board is pics of my exhaust. If i get time tonight i will try to find them.

Re: installing a 440 mopar in a cj7

I thought that:

1) The 440 was the same block as the 318, and

2) The 318 has been done several times.

Have I had tee many martoonies? MOPAR engines are not soemthing I pretend to know much about.

Re: installing a 440 mopar in a cj7

No, the 318 is the more modern LA block. Unless you are talking about the earlier 318 A which were much different than the 340/318/360 LA motors. The 440 (RB or raised B) has its roots in the 383 B block, a much larger, taller chunk of iron. The 440, it has one strong block for making power, but I can't imagine that being the utmost priority in a jeep.

Of course I was thinking of the OLD 318! [img]/ubbthreads/images/graemlins/codger.gif[/img] I thought that it was eventually taken to something larger than the 360. I'll stop thinking now> [img]/ubbthreads/images/graemlins/blush.gif[/img]
