To make a long story short, I pulled the engine out of my buddies 99 rolled xj, and used the block for another project. So now I have the intake manifold, head, exhaust manifold, etc. left over. Can I use any of this on my 89 comanche?

 

check out the throttle body setup between the two, you may have to throw a newer tb at it if you can/ would want to. the head you can use, and the exhaust manifold you should be able to use, as long as its the same setup as the old one

 

thanks, I still have the throttle body from the 99 also, so I have that if I can use it
