318 swap in my CJ

Ok guys, dumb question time. Rebuild for the 85 is in the planning stages. Will a 318 from a '97 Grand Cherokee fit? I have a 258, T4, D300.

it'll fit. you'll just have to figure out what tranny will bolt up that you can get an adapter for your x-case. a ford or chevy swap would probably be alot cheaper and easier because of adapter parts availability.

Re: 318 swap in my CJ

I think that the motor mounts will be the toughest part, but the Ram truck mounts that bolt lower to the block should work with a custom fabbed purch. Bolting the t-4 to it may be tough, and probably won't hold up very long. You can direct bolt up an AX-15 with a Dakota's bell-housing from a 3.9l. You can also direct bolt a NV-4500, and NV-3500 using a Ram's bell-housing. You could also try a Dodge version of the NP 435 using a Rancharger's housing, and notching a hole for the crank angle sensor. The advantage to this is all Magnum engines are roller engines and come with sequential port fuel injection!

Re: 318 swap in my CJ

Thanks for the input. I guess i knew it would "fit" just getting the trans to bolt up will be the tough part. I guess i'll skip it or start saving for an NV4500. Saw it on ebay. If I can get a v8 cheap I'll do it, otherwise the 4.0 head swap looks like the answer. Thanx

Re: 318 swap in my CJ

I want to do something similar (sb MoPar/TF727) with my CJ-7 eventually. What I want to get though is the 360 crate motor (380 [img]/wwwthreads_images/icons/shocked.gif[/img] horsepower) from MoPar Performance. Will a "Chrysler" pattern 727 bolt up to my Dana 300? Or is there an adapter available? Just thinking out loud again.[img]/wwwthreads_images/icons/cool.gif[/img]

Re: 318 swap in my CJ

yes they do. infact the tf727 was used in some jeep wagoneers during the 80's. elusive used one of these in his jeep and the dana300 bolts right to the back of it. if you go the mopar route you can get the dodge 727 and find a junked jeep wag to steal the 727 from and install the jeep 727's tail housing onto the mopar version. this will give you a 727 that will bolt to your dodge motor and also to your dana300. i'm sure advance adapters makes a kit too.

Cool! Thanks Brian, I knew there had to be a "junkyard way" of doing the trans to t-case hookup.
