Re: [Amc-list] Late engine/trans into earlier body...(83 Spirit running gear into a 1963 Breadbox)

" The only more or less modern engine that is an easy fit is the
" Ford 200/250 six.  Swap transmission with it.  The late model 250
" uses the SBF bolt pattern and could use an early model AOD or a
" five speed.  I wouldn't use a 200 unless it was free/cheap -- not
" much more power than the 196, but parts availability is of course
" better.  May as well go with the 250 and get the benefit of the
" extra inches.

nb. all 250s have the sbf pattern.  very late 200s do too, but missing
the center top bolt because they're so low; most have a small pattern
shared with the 170 and taking only a 9"-ish clutch.  amc content:
stock bellhousings take the ford-version t96 and t150 toploader; i
don't think there was ever one for the sr4/t4/t5 but there certainly
are adapters, courtesy of the mustang fraternity.

up to about '65, the 144/170/200 had 4 mains like the 196, 7 in later
170/200.  the 250 always had 7.

the stock 200 probably isn't up on the ohv 196 for power, but it
weighs a whole lot less; i wouldn't wonder if it was more than 100
lbs - '60s tech vs. '30s.  and while the stock head with cast-in
intake is comparable, there's the cool aussie/argentinian ford 12-port
head, the cooler aussie crossflow redesign, and the coolest aussie
ohc/efi re-redesign.  the 12-port is a straight swap though its
matching 2bbl intake is way too wide for an early american; the
crossflow can be adapted to north american blocks with a little work,
similar to a 4.0 head on early 258s.  btw the ohc is based on the 250
but shrunk a bit down to 4.0L.

i think one could adapt the efi from a late 300 to the 250 or 200
without much problem.  you'd have to start with the 12-port or
crossflow heads and fab an intake, but you'd have to fab an intake
anyways for the narrow american - a swoopy 300 style would look and
fit well!  scaling the injectors to the smaller engine isn't hard and
there must be an appropriate throttlebody from some ford v6.

another short modern straight six is the mopar slant, but leaned over
as it is - 30* - it's not very narrow.  trannies used with it are
afaik all new process until the late '70s when mopar also used the
t150, but with a mopar bolt pattern.
