I hear what you're saying. But one thing I have noticed with most newer vehicles, is that on the highway, the bigger engines do about just as good on gas mileage since they can run at lower RPM's and consume less fuel making them more efficient. In the city, especially in winter climates, yea the smaller engine will excel in gas mileage. but on the highways, it's not too much different.
I love the 4.3, that'd be a good swap in a Jeep too, and I know it's been done. The 4.3 is designed off of the small block 350, it uses the same bore even. I know quite a bit about s10's.

That would be sweet but I have a 2.8 at my disposal and all it may cost me is a 12 pack of beer .

There's a few things they have to swap over...but if you already have access to a 2.8, it'd be better than a 4-banger.

I remember reading about the 2.8 chevy motors in cherokees,do you know if they used a borg warner tranny or did they use an AMC product ? Googling but not really finding anything on that .

You are correct that AMC did source parts from other makers. Taken another way, it helps to keep costs down (and profit up) to use a distributor from GM or a Borg-Warner or Chrysler automatic transmission (both examples on late 60s /70s AMC) or later a Ford sourced ignition on the original YJs. Why engineer another part when you don't have to? Ask yourself why does Motorola supply alternators to many makers?

If AMC made a mistake, it was the 70s Matador coupe that sent the company down the tubes. Nice enough car (and I like Teague styled cars!), but it just didn't sell enough to justify the cost of producing it.

Another thing that really hurt AMC was the UAW. Yeah, that's not a PC subject to bring up in today as the U.S. races for equitable re-distribution of everything, but the UAW really bent AMC over. Those costs drove AMC into the arms of Renault and the rest is history.

With rare exception, AMC engines are AMC produced (Iron Duke 4-banger from GM for an exception). The 390 V8 was not a Ford engine, etc. The bodies were all AMC and they had many innovations (first all plastic interior is a weird example, but all cars are that way now).

Chrysler bought AMC in 1987 for one reason -Jeep. At least give AMC props for keeping Jeep alive after mismanagement by Kaiser.

JODY HOWLAND I have a 90 model also and I recently upgraded to hei ignition and it is a gm part

deathphoenix99 ^Yea, the steering columns in the older jeeps is the Chevy truck column, I've grabbed parts from one in the junk yard once for my truck.

Yes, I'm a new Jeeper, so I'm learning all about the ins and outs of my YJ.
05-20-2011 11:00 PM
superduty_5.9 Yes if it is a 2.5 4 cyl then it is a GM engine. Same one in the S-10's. Later 2.5's were different.

This is very true. Not unusual to find GM or Ford parts in the AMC years.

Irongrave last time I checked the YJ was an AMC product. the Mopar influence didn't hit until 92 and even then still mostly an AMC product. and being an AMC product they sourced a lot of GM
05-19-2011 05:19 PM
HotRod90YJ So this kind of thing is normal? I wasn't sure if this was common, or if the PO made a bunch of these changes, which could be the reason for the problems I've been having with my jeep.
05-19-2011 03:50 PM
94impactyj stock radiator cap is a GM part as well.

GM parts on a Jeep

Had my Jeep for a few months. Had it tuned up, but had to get GM hoses to replace the old GM parts that were there so it would match up. Having some minor issues now, ordered a coil, but it had to be a GM coil to match up with the GM distributor. The guy even told me today that there weren't any Jeep parts on it, mostly GM. How can a Jeep (Chrysler) support parts from another make (GM)? Has anyone else run into anything like this?
