A: The easiest way is a Toyota Landcruiser/Lexus SUV 1H-T motor. 4.2L turbo 6 that came bolted already to the AW4 trans. make motor mounts, exhaust, cooling and wiring changes, and it's good to go! That, or a Duramax 6.5 (GM/Isuzu buildup) My latest issue of Off Road Adventures has most of the scoop on recent diesel engines. Kevin, Appreciate the input. A 6.2L Diesel wouldn't be a bad plan, they are a bit heavy and not the most fuel efficient. I think I'd go with the 6.5L TD if I were going with a V8. If I went with the GM Diesel I'd go with a newer 700R4 out of a big Blazer... my '83 GMC Jimmy was a pretty decent rig... but I never got it over 20mpg... :( I wouldn't run a TH400 and QT, my axles are wrong... and besides I'm not a big fan of TH400's or Borg Warner QTs. I wouldn't put a 727 in my Jeep either... I've replaced too many in my FSJs. I am totally disillusioned with "elephant" power, at least in the Jeep versions. I want an overdrive tranny... I've been in overdrive... I can't go back... :) The Nissan 3.3L is an ok Diesel, but seriously underpowered. I'd rather use a Mercedes Diesel if I was going with underpowered. :) I like the AW4 transmissions... And as a fall back I could use my old world class T-5 that was behind my 4.2L... although I really want (and need) an Automatic... :( john Kevin Pekarek wrote: > On Tue, Aug 03, 2004 at 11:12:06PM -0700, john meister wrote: > >>on the drive from Snohomish (Seattle) to Spokane we got "only" 38.43 mpg. >> >>Tomorrow we turn around and head back... if we don't have the headwind >>we have last time I might even share what I get on the way home. :) >> >>I'm giving some serious thought to going with a Diesel engine in my >>'83 J10.

The 6 cyl uses a different pattern converter than V8 (6 is evenly patterned and V8 is offset due to the balance weight, even though the weight is on the flexplate) As for lockup or not, check the input shaft of the trans. There is a center hole over 2" deep on the lockup. If it's less than that, it's not a lockup. The guys who know their Jeep 727 stuff are Sea-Tac transmission out here in WA. 253-839-4967 (Pacific time) The '81 and newer are lockup capable, but not all are lockups. BTW, you'll have to clearance the passenger's side of the 727 pan to clear your driveshaft for the D300 unless you have a front axle that is slightly more offset to the right than stock. There is supposed to be a kit to lockup the converter at low speeds for coming down hills so you don't overheat your brakes. I just heard about it in passing the other day. You'll need the matching flexplate to your motor (304 for 304, 360 for 360, but 258, 242 and 232 all share zero balance) in place of the stock flywheel for the std trans.

I think right now the fan pushes air away from the alternator, and it runs hot, and doesn't charge like it should. Any thoughts on this ? - -Landon 89 GW Austin ------------------------------ End of fsj-digest V1 #2205 **************************
