crazycanuck

i HAve a 360 that i am going to put into a j10 with a 258...does the 360 use the same bellhouseing that a 258 does? Will i need a new flywheel? i plan on working this engine pretty hard should i put a better radiator or just custom build one?

Yes
Yes and
Yes!! At least a large 3 or 4 core!!! You don't need to custom one, you can buy them cheaper. A stock 3 core OEM P/N J5356049 is $223 at http://www.teamradiator.com/cgi-bin/tr/process

you'll need to move the rad support out on one side, you'll see the 2nd mount hole in the bottom of one of them, right side i think. :-|

One vital piece of info here..I did this swap and yaa it's a "bolt in " but for one detail..you need to check the tranny Length.. Mine had a T-176 and when the engine was bolted to it the heads hit the firewall.. You need the longer input shaft (T-177) as the six fits into the firewall notch and the eight doesnt.. I moved the engine /tranny mounts forward 4" and extended/cut drivelines as needed.

?!?!?!?!?!?!?!Forward 4"?????????????? Did u use the standard mounts in the right place? First I've heard of this one and I'm about to do it with the V-8 mounts in an '85 CJ7 frame

into a J10 v8s usually do have a much longer input shaft. Same reason you cant use the v8 t18 from a FSJ directly into a CJ. The input shaft is to long. But you could use the 6cyl t-18 from a FSJ into a CJ, it is only 1" longer than stock then You have 2 choices really, get the correct tranny, or move the tranny forward and hope you could modify the shifter properly to still work I have only done the swaps in CJs not in FSJ's -Paul

Yep, I used the Correct Motor mounts , Pyagid is correct.. I am not sure how the CJ works out, I looked at mine and it seems like there is a lot more room for the 8.. But I know the heads hit the firewall on the j-10. I could have gotten away with three inches except for access to the rear valve cover bolt..So Investigate carefully. I left the tranny crossmember where it was, and built an extension onto it.
