cerial Posted December 18, 2016 Share Posted December 18, 2016 I have a 88 Mj with 4.5" of lift with a 4.0 under the hood mated to a ax15. I picked up a 355(350) out of a yj from a kid that had advanced adapters bell mounted to the jeeps ax15. The 355 did not break anything in his yj. I think I am safe running it. I got everything carb to pan engine wise including yj 350 headers and have the bell fork, pilot, and entire clutch. Basically everything except for the master and slave cylinders. The kid has a new piliot and some other part I still need to pick up from him. I plan on doing the swap as soon as the snow is gone and want to make up a shopping list now so I have things around ready to go. I am planning on using advanced adapters bolt in motor mounts. I think I can use the yj headers. They are not block hugers. They dump out towards the firewall. If I can not then advise me please. The 2000 Cherokee slave that I retrofitted (only 3 hours run time) is what I am stuck on. The fork is moved to the other side. Am I just throwing a compression fitting in there and moving the line and slave to the other side? Or do I need a different slave to work with the bell. The yj was using some kind of Toyota slave. I want this as bolt in and go as possible. I can justify the added cost of using bolt in parts then fabricating stuff. That being said if there are tricks that you guys know that could save me a few hundred it is worth asking about. I upgraded my fans to dual electric while back setting the radiator between the headlight buckets right behind the grill. Planing for this engine swap one day. This moved the radiator forward 2". I can toss those electric fans and might be able to fit a 7 blade clutch fan just not sure if that would keep it cool enough or if I should go with a different radiator from the start. Here is a picture of the current radiator and fans; Link to comment Share on other sites More sharing options...
husky410ohio Posted December 18, 2016 Share Posted December 18, 2016 Please take some pictures I would like to see. Sorry can not help with the slave cylinder I have the McLeod hydraulic throwout bearing. I used the advance adapter motor mounts and headers. If I would do it again I would use cast iron exhaust manifolds. It is a tight fit. Link to comment Share on other sites More sharing options...
cerial Posted December 18, 2016 Author Share Posted December 18, 2016 The engine is outside filled with coolant in the bed of the Mj right now buried under a foot of snow. I will try to take some pictures of it next weekend. I have a old set of Ramhorns I picked up at a garage sale for $5. The ram horns kick out more in the middle where as the yj ones kick out more towards the rear of the block. I think the yj ones are 2.5 where as these ram horns are 2".

husky410ohio Posted December 19, 2016 Share Posted December 19, 2016 The rams horns would be great let me know if it fits I want to to the same. Another member posted pictures about 10 years ago and he had the type that go up and exit in the back. here is the picture: http://comancheclub.com/topic/1688-this-is-what-a-350-looks-like-in-a-comanche/?hl=picture008 Link to comment Share on other sites More sharing options...
1989 comanche mj Posted December 20, 2016 Share Posted December 20, 2016 I would use the advance adapters stainless braided line and conversion fittings. I have a YJ with 383, went with the hooker custom headers that exit to the rear like manifolds but have a 7004 transmission. Link to comment Share on other sites More sharing options...
