86 Comanche Troubles! Please HELP!

[mattnw94]

Okay so I just bought my first Comanche! My dream truck! So obviously I am excited but need some tips... It is a 4 speed with a 2.8 motor.  I drove it home and, had to call a tow truck not to far into the drive after a horrid noise occurred and started over heating.

 

1. Does anyone have a 2.8 for sale?

2. Is there a motor that will bolt directly up to the trans?

3. Is there any better options for me as far as a swap goes?

 

--> Any tips are extremely helpful seeing that am not super knowledgeable on Jeeps, more Ford and Chevy

I believe that both the gm 3.1 and 3.8 will bolt up to your ax4 with your current bell housing.

the 3.1 and 3.4 are the ones to look for (mid 90s camaro/firebird or S-10).  it's a better block design and will accept all your accessories/exhaust/intake and bolt to the trans.  only caveats are that your truck has a mechanical pump on the engine block and so you'll need to add in an inline electrical pump and then your current flywheel will need to be neutrally balanced by a shop (the 3.4 is internally balanced but your 2.8 uses the flywheel as the balancing mechanism).

If you're knowledgeable on Chevy, you're in luck.  That POS 2.8L is a GM/Chevy engine.  As mentioned by Pete, if you're in search of a replacement engine, do yourself the favor and scout out a 3.4L from a mid '90s Camaro or Firebird.  It'll be the easiest swap you can do to rid yourself and your MJ of that horrible excuse of an engine.
