Re: Have '89 jeep cherokee engine maybe trade for '92 cherokee engine?
Sure can't, Bill. I've never laid a 258 head alongside a 4.0 head.
You can see the difference between the 88 and the newer HO with the
vehicles sitting side-by-side but I've never looked at 258 that way.
When I was looking, I had a line on a wrecked 91 XJ with under 45k on
the clock but I was too new at this to really realize the power
difference and figured it was more work than it was worth to swap
stuff around. Looking back...
