not just electronics.  remember the crappy gm 2.8 v6 in the first
cherokees?
http://en.wikipedia.org/wiki/GM_High_Value_engine
is what it's grown into.  the 3.5L lx9 is 200 hp, 220 ft-lbs; the 3.9L
lz9 is 240/240, and they're still pushrod and 2 valve.  but they have
3 things the 4.0 didn't - roller lifters, knock sensor [okay, the 4.0
had one and lost it], and variable cam timing.  and there are
displacement on demand variants.

" But if you look at the last iteration of the 4.0 Jeep engine that

i know someone here or on the strokers list has done it, a
daddy/daughter project painted purple.  i believe it was her first car.

i'd suggest an early '90s yj wrangler donor.  they have a 'normal'
accessory layout [unlike the cherokee] and the auto is still a 3sp
all-hydraulic 32rh/tf999, so it'll play well with the pacer auto.  and
around here at least, obdI engines don't have to pass smog.

i've seen the 226 specs - bore 3 5/16", stroke 4 3/8"...  it was one
of a family of fours and sixes with different bores and maybe
different strokes too and i think even ohv versions - it was made for
many many years as an industrial engine.  i didn't know kaiser owned
continental; that strengthens the idea that the 226 and 230 are
related.  iirc journal/bearing sizes are the same; the 226 was a
4-main engine too.
