ZZ4 350ci and SM465 swap adventure

Well here goes.
I am going to try to document my attempt at installing a turn key ZZ4 350 married to a SM 465 Muncie. My plan is to run my 231 with sye for now.

Please keep in mind this is my first jeep and I have never done anything like this before. So I will learn as I go and I will learn vast amounts of info from all my friends on this forum. I am by no means a Mechanic but I have been a Machinist for 25 years so I understand how things work and I certainly understand fits and tolerances and how critical they are to proper machine function. Only one thing I know for sure is that I WILL make plenty of mistakes....but I learn best that way!

A little history on the heep:
87 Loredo 258. 8.8 with 4.11 and Alloy USA axles, OX locked.

Front axle is d30 with full solid chromo axles also ox locked (I have not completed the front axle yet, all the upgrade parts are on a garage shelf currently)

The Motor





The tranny







Much much more to follow stay tuned!!

Strong motor, great tranny. Attention to detail, again and again. You won't have a problem with the install. Ron

Thanks for the words of encouragement.
Wow this post is a dead horse. Maybe this has been documented so many times that nobody has any interest. Hmmm maybe I shouldn't waste my time doing the write up.

Last time I checked AMERICA was still free, Opinions are every where. I like the idea of the build. If the others don't like it, they don't have to read it. Off topic, A good friend of mine has a 89 yj, and a heavy foot. The last small block broke the bell housing, sbc/465/44's, now he wants a big block. I say build it, document it, wheel it. love it.

WAIT!!! What happened! DID IT WORK????

I had so much hope for this thread as I am looking at this swap too.

1) how did it go? Any hang ups?
2) What do you think of the motor?
3) Any reason you did not do the LS swap instead of this? (COST?)

Would you go this direction again???

Come back! I care!

My Scrambler has a 40 year old 350 and a fairly low miles TH350. I'd really be interested to hear about your experience.

Well the swap is done and roadworthy. I am extremely happy with the final product. I am waiting on a front driveshaft from Tattons. I just got my oil filter relocation kit from Summit Racing today. The front shaft will hit the oil filter otherwise.

1) how did it go? Any hang ups?
2) What do you think of the motor?
3) Any reason you did not do the LS swap instead of this? (COST?)


I freaking love this motor!!! Rolling burnouts at will. Gotta love roller motors!
Oh yeah I didn't want to spring for an LS. This motor is a great platform fo future upgrades if I want to.
