I started with a 304 in a CJ. Then I put a fresh 360 in that CJ, and now I am running a fresh 401 in a Wrangler. I would highly recomend the 360 if its in good shape or if you are going to rebuild one. The 304 was ok but the 360 was a major improvement and will cost the same to rebuild as the 304. Well worth the effort and you can find parts easier then the 401.

Thank you, I think you are right in that the 360 would be better for him in that 5 (his first jeep) w/a stick.

Still trying to work out the TH-350 to go in it.

Thanks again everyone for the help,
Jim

TH-350 is going to be expensive when you start adding adapters to bolt to an AMC. I put a 727 in mine out of a wagoneer and was able to bolt a DANA 300 to it with no adapter. A CJ-5 gets pretty short with an automatic especailly if you have to start adding adapters.

Agreed. We were going to swap out the entire drive train and go chevy w/a D20 on the back of the tranny and only use one adapter, OR, use a 208 case and no adapters.

I just need for him to decide what to do. would just be easier if he would go the 360 and I give him my TF-999 and I bolt in a TH-400 in the CJ8.

How are the DS clearance on a TH-400 w/a D300 and will a D300 bolt up behind the TH-400?

Dana 300 won't bolt up to a th-400. There is a stock adapter that is hard to find and not very strong for a Dana 20/th-400. I have a Quadratrac th-400 and was originally was going to use it, but I found out the after market adapter for a 300 or the 20 was over $500 and you pretty much had to rebuild the tranny to put the correct output shaft in the tranny. Thats when a found a guy with a 727 still in the factory crate for $500. It was a no brainer at that point. Bolted it to my 401 and I haven't had any trouble so far.

Ok thanks,

Not sure what trans he has in his '74 (3spd) but I do have a '86 258 in the shop that needs one cylinder. I wonder if his 3spd will bolt up to that motor. If not then he will have to rebuild my extra T-176 and find a D300.

Thanks again for all the help,

OK leakdown test 100% FAIL !

TDC on compression stroke and 15psi of air = air coming out of oil filler tube. When I close off the oil filler tube I can hear a little coming out of the carb as well.

The plug we had in question (cyl 3 on the passenger side) had some oil on it and I did not even have the wire hooked up-oil was clean and that is the cyl I tested for the leak down.

So we are not going to mess w/the engine any more.

FOR SALE if any one wants a engine to rebuild.

Thank you all again for the help,
Jim

P.S. Now the fun starts

Installed a breather for the TF-999. Also put RTV on the threads etc.

Installed a 3/8"x fitting.

Doesn't work-T-Converter hits the 90 and it will not let it seat all the way. You can bolt it up but the T-converter won't spin.

I read a few write ups on this but .... Just wanted to let some of you know.

I'm confused. What is the purpose of drilling a hole in the front pump?

The hole is already there-breather. When and if you get that far under H20, then H20 will enter.

I just threaded/tapped the hole and it went well until the T-converter hit it. It shouldn't have but did.

So we removed it.

Well we got the motor and Trans in tonight and the cross member bolted right up. Thought we would have to drill new holes.

Nice project

I have read many times that an automatic will not work in a 5 due to the OAL of the engine/trans/xfer case without having a very short rear driveshaft.

Will this be a problem with the current 999?
