Re: [Amc-list] 71 Gremlin 232

[Jim Blair <carnuck@xxxxxxxxxxx>]

Don't forget '71 was the last year of the small bell pattern engine! Wasn't there an issue of the '81 up split intake/exhaust fitting the earlier engines? (linkage issues?) Will the Renix (and/or HO) intake clear the power brake booster? (later models like my '82?)

On my own car:
I'm in the market for a Model 20 for my '82 Spirit (near Seattle) for the same reason. I just had to get a shop (Randy's Ring and Pinion) to fix the rear wheelbearing on my Model 15 (they called it a Model 35) but since I'm pumping up my motor (4.0L head with EFI and 2wd AW4 auto) I figure I need to get started on strengthening things now before my right foot gets too heavy!
I thought about using the 2wd 727 I have (from a postal Jeep) but they are too power absorptive for my liking.

there's lots you can do, starting with the good '60s factory carter
wcd 2bbl setup, the better late '70s carter bbd setup, or the best
'80s bbd one.  they can be further boosted with larger carbs; mopar
used a bigger bbd and a compatible holley 2280 on some pretty
fair-sized v8s, and the carb base is a common pattern also used by gm
rochester 2bbls.
 
or you could go for an offy 'dual plane' 4bbl intake and 400-500 cfm
carb.  there are some other 4bbl intakes but imho this is the best.
 
cliffordperformance.com has a triple sidedraft weber intake.  they
also have amc car exhaust headers.
 
or tbi, on any of the 1, 2, or 4bbl intakes.  holley makes ones, or
you could adapt gm.
 
or [probably] the mopar mpi kit originally aimed at the '80s 258s.
 
there are lots of cams for the amc 6.  do a little internet research
on motor oils, zddp, and cam failures first though.
 
you can also easily upgrade your ignition, to either the '78-up
duraspark style with 'tfi tuneup', or a late '70s chevy straight-6 hei
with your original delco drive gear.  with either, you'd want to
recurve the advance mechanisms; you can unlock a surprising amount of
free hp.
 
" As a second option can I hook up a 304 to the
" really nice B/W Flash-O-Matic currently in the car, or would I need to
" replace the trans with the engine? Is this an easy change over?
 
2bbl '70-1 304s had a very similar aluminum auto, but i don't know if
it's close enough to use the six's instead.  an engine+tranny swap
would be surer, and you could also go for the easier-to-fix '72-up
torqueflite auto.  imho the v8 would really want a stronger tranny
anyway.
 
if you wanted to do an engine swap but stick with a 6, a jeep 4.0
stock or stroker [with 258 crank and rods] will drop onto the 232
motor mounts - at least, up to late-'90s or so blocks.  you can easily
build a street-friendly 4.0 stroker with over 300 hp.  the 4.0 is a
direct evolution of your 232 and such a slick swap few onlookers would
realize it wasn't stock.  you'd also want a stronger tranny with
these; wranglers used a tf999/32rh/32re related to the amc
torqueflites, cherokees a strong 4sp aw4 related to trannies toyota
widely used.  cherokees have a funny fan setup you'd want to change
over to wrangler style.
 
you'll also want a v8 rear and a general brake upgrade if you bump the
power much.  good news, a '79-'83 concord/spirit brake system is a
bolt-on - if you get -everything-.
