Mr_Random said:If you want stick, look for 88 plus, either Renix or HO (I'd rather have Renix). If you want a purely street cruiser, get a 2wd. Long bed's are okay with 2wd, but not preferable when trying to make a competent offroader.
If you want the most efficient real jeep (not the patriot and compass crap) ever made, try to find a 2.5 2wd 5 spd (much more common on MJ's) short bed, any year will work, but 90+ is preferable.
As previously stated, any automatic 4.0L will be bombproof and fun no matter what!
Definately look for the towing package or one with a D44 rear, you'll get a much better rear axle from it!
Mr_Random said:okay yeah, I wasn't sure if that's what it was called... There is one in town that NEVER moves... Long bed 4.0 d44 4wd and sits a little higher in back... In freaking perfect shape... If it wasn't in a scary neighborhood I'd go to the door and ask if they're selling... I'm jonesing so much right now! Haha...
Mr_Random said:5-90, what is the last paragraph about? the 2.8 IS a GM engine with a GM bellhousing... the AMC 2.5 (I'm thinking 2.46 is right, but I'll say 2.5 to ease some confusion) IS an AMC/Chrysler engine with the GM housing... Were you thinking the Chrysler 3.8 instead?
and yeah, I screwed up the date for the ax-15... I knew it was a half year, but thought it was 88.5...
Oh, and you know too much stuff... I thought *I* knew too much crap about XJ's and MJ's!!! I don't think I'll ever stop stuffing more info in my brain though...
5-90 said:OK - perhaps I'm missing something here. Which bit about the last paragraph has you buffaloed? It's a lot easier to explain something when I know what I'm explaining...
The AMC 150ci I4 was originally marketed as the "2.46" engine to differentiate it - not only did all of the Big 3 have a 2.5L four-cylinder at the time, but AMC had use the GM/Pontiac 151ci 2.5L "Iron Duke" 1980-1983, so that's immediately before. Just about all of the AMC literature will call it out as the 2.46L engine (I think just about everyone has used a "2.5 litre" displacement at some time or another - my wife's 2005 Suzuki Verona has a 2.5L GMDAT inline six wedged in sidewise. It was the double-roller timing chain setup that sold me on the car - it's not a damned belt. Belts are for pants, not timing. They're also useful as accessory drives.)
The 2.8L V8(?) block uses the "Metric GM" pattern - that started with that engine. It was also used on the 3.1L and 3.4L V6-60 engines, and I think it ended up on the 2.5L/151ci four as well for a bit. It may have ended up on the AMC 2.46L for a bit as well - but I'd have to check notes on that. The 2.8L in the XJ got a ChryCo slushbox when it got one (the A904/A909,) and it was a Chrysler box with a GM bellhousing - no relation to the ChryCo 3.8L that I know of - nor to the 238ci/3.8L V6 they came out with for trucks, which is derived from the LA block (and uses the A/LA block bellhousing pattern, same as the 318/360, 488/505ci V10, and other A/LA-block engines.)
So, if you'd let me know what I need to explain, I'll dig up my notes and see if I can't get it to make sense for you. I've no trouble doing that - I just need to know what it is I need to do it for.
(There's nothing wrong with constantly learning - it's the same way I go. Probably got started by my granddad - a polymath, autodidact, and a true modern "Renaissance Man." I've tried to be the same way. The principal reason I know so much on this subject is because it's all research for my second book - http://www.geocities.com/JeepI6Power/swap.html. It keeps me busy...)
Oh - and the AMC 2.46L/2.5L four was also used in the Dakota until sometime around 2000 as the four-cylinder option. It was marketed by ChryCo as the 2.5L, which lead to more confusion. The 2.46L four was the second-from last AMC engine in production, with the 242ci/4.0L six being last - MY2007 - and the AMC 360ci V8 being the last AMC V8 in production in the SJ until MY1992 by ChryCo. Confusion again - it was marketed alongside the ChryCo 360ci V8 in their trucks...)
I pulled my D44 from a "metric ton" MJoffroader461 said:its called a Metric ton package and they are not a 3/4 or 1 ton...still a compact pickup with 2 extra overloads in the rear packs and heaver load capacity...everything else IS the same.
My '87 with the 4.0 and AW4(auto) is on the floor.ScottyDog said:Or are the other AUTO MJs out there on the floor?
Mr_Random said:OH, I misread it and thought you said "The 2.8L is a "special case" - a Chrysler engine with a GM bellhousing," rather than transmission. Me thinking you said engine led me to think you were confused... because the 3.8 oddfire did come in the CJ in the early 70's I believe... ah I'm confusing myself...
The 2.46L (for simplicity's sake, the 2.5, because everyone thinks "XJ website, talking about 2.5L, it must be the AMC four cylinder," not "oh, it's a pontiac Iron Duke!" or any other 2.5 that has ever been made...), as far as I know, ALWAYS had a GM metric bolt pattern, even on the 96-00 Dakota, sporting with it the odd ax-15 with GM bellhousing combo.
Yeah yeah and the AMC V8 went the way of the dodo with the release of their last vehicle ever designed, the ZJ in 93, which took... um... 4 years(?) to get it's own 360, tagged as the 5.9L... shared with the durango...
Wow I think we ruined this thread... I still love comanche's... the only thing that could come close right now is if someone decided to turn their LJ into a jeepster remake... A Half top with enclosed bed, that would be sweet...
xj_dummy said:Thanks for your help. I have been looking at an 86 with a 5speed 4 wheel drive for $1000.00.
Dont know what engine it has yet?
Mr_Random said:Looks like he might buy it, 2.5L, ax-5, np207... basically my XJ in truck form!
Oh, I know the ChryCo 5.9L has nothing to do with AMC... that's what I meant that the AMC 360 went the way of the dodo...
