The engines are the same basically so you could just swap over the
electronic parts to the 89..... I would just swap over the 'engine' and leave the intake and exhaust headers including the fuel rail, distributor and parts and alternator from the 92 in there.

The intake and exhaust aren't the same. The 92 used the HO head and
the mainfold/headers won't match up. Just looking at my 88 next to the son's 91, nearly everything else will swap. I looked at this idea a couple of years ago and decided that the only really easy way was to swap heads onto the good block.

Ahh ok, good to know, thanks. I knew the ports were different but
didn't know the headers were. So only the short block will swap then. Man I got this 258 with a new crank sitting in my garage and an 88 4.0 getting tired..... Stroker, mmmmm......

The HO intake manifold is a whole lot nicer. The flow geometry is
nice and symetrical. Between that and the port angles they got a bunch of ponies to add to the 4.0. Not that I would sneer at the umph of the '88 head on a 258 block...

I am thinking the guts of the 258 into the 4.0 block making it something
like a 4.7 'stroker'. :-) It would be worth it to just swap the short block for the OP then eh. Keep the head and intakes and swap from there down. Even if the head needed a valve job, that isn't much. Mike Will Honea wrote: > > The HO intake manifold is a whole lot nicer. The flow geometry is > nice and symetrical.

Hi Will,
Can you tell me if the '88 frog injection looks like it fits the regular 258" head where intake, and larger exhaust ports and manifolds are in align? http://web.archive.org/web/200210011...inder_head.jpg Rather staggered like the 4.0L: http://www.off-road.com/jeep/tech/en...adconv/146.jpg God Bless America, ßill O|||||||O http://www.billhughes.com/ Will Honea wrote: > > The HO intake manifold is a whole lot nicer.
