Small block Chevy Jeep

[old guys rule]

Does anyone still make adapter kits for small block Chevys and a Jeep?

Yup. Advance Adaptors in Paso Robles Ca. Or you could do like I did on my father in laws 86 CJ7. Put a 5.2 [318] in it with EFI.

I have used Advance Adapters and Novak Conversions out of Logan Ut , Both are good . Do some research about complete drivetrain compatibility , some combos work a lot better than others . My '49 cj3a has 4.3 v6 , th350 , custom dana 44's , 6 inch body/frame extension etc.....

Building jeeps is an easy rabbit hole to go down......I put a 318 in my wrangler with mostly stock off the shelf parts. I called advanced adaptors and asked them if they offered a mopar conversion kit , they said no. then about a year later I saw them offering one. I beat them to it. all stock parts. dont use a chevy motor its been done to death

When I did the 86, had to make up my own front mounts. Trans was easy. The Jeep had a 4.2 [258] with a 904, so I got a different case for it. Didn't have to mess with driveshafts.

@ckessel Were you around pismo during the late 70s early 80s ? There were a bunch of us from Santa Barbara that hit the dunes every holiday weekend . We had all variety of vehicles , mine was 1974 Dodge W200 - 440 stroked to 481 cid , 6 pack rods , 9.0 arias pistons ported 906 hds 2.14 & 1.81 valves , .570 solid cam , Harlan Sharp rockers , Torker with 800 double pumper , Direct connection " Hemi converter " TF727 , paddles in the rear etc ... Jay Roach (RIP) in Montecito welded and offset ground the crank and Rich Ryola ( spelling ? ) in Santa Maria did the final machine work .

Oh yea .. we were also the originators of the " Pismo State Beach Dune Patrol " . I Didn't want anyone thinking that my GMC in my flatfender made me a total traitor .

I'm going through decision making process now. I'd like to do a Gen3 swap, the numbers aren't out there like LS combos.

 

[fewillys]

Hey Fury what year and model of jeep are looking at swapping into ?

Not to hijack this thread, but I have a 318 with a 46 RH out of a 94 Dakota that I'd like to stuff in my wife's 99 TJ. Anyone know if this might be a really bad idea, or is it doable, without a lot of pain and swearing? The motor in the TJ now is the 4 cylinder, and that little turd wagon couldn't pull your hat off your head...

Right down the rabbit hole....

Sounds like a lot of work. I am definitely not a fabricator

 

[ckessel]

It was fairly straight forward. The cj had the 4.2 with a 904 behind it. Had it re-cased [rebuilt too]. That kept me out of the driveshaft and adaptor fun since from the trans back, nothing changed.

Pirate 4x4 forum has tons of info on just about any swap . https://www.pirate4x4.com/threads/5-9-magnum-swap-mini-bible.1132282/

The CJ has an AMC 360 (straight bolt in).
The TJ has the 4.0
Just my opinion, but I like keeping the
bloodlines pure. A lot less expense and
fabrication when upgrading engines.
