Re: [AMC-list] all's quiet on the western front

I was about to reply to the 240/250 but I see you got that covered. It's funny that Toyota should come up as I just picked up an '89 Tercel for a daily grinder (at least for the longer trips without a load) I am planning a 2LT diesel and AW4 or AX-15 in an '86 Comanche that currently has a 2.8L but it has to wait till I get rid of at least 3 of my other projects/parts cars.

" From: Frank Swygert <farna@xxxxxxx>
" 
" The M series had a 75 mm (2.95") bore all the way through the 3M (M,
" M-E, M-T, 2M, 3M -- 1965-1980). That alone makes it 3/4" SHORTER than
" a 196, but I think the overall length of the Toyota six is still more
" than the 196, but I could be wrong. 
 
are you figuring the thick 196 cylinder walls in?  the m certainly
can't be bored .125" over like the 196 can; probably not more than
.040" -- 1mm.
 
" All those were only 2.0L (1988cc, 121 cid) except the 2M, which was
" 2.3L (140"). At those sizes, may as well consider a four cylinder. 
 
except an i6 is smoother.
 
" The 79-88 5M and 5M-GE are 2.8L (83.1 mm bore); 6M-GE is 3.0L with a
" 91 mm bore, 7M-GE and 7M-GTE 3.0L with 83 mm bore and longer stroke.
" The "T" is for turbo. 
 
the 5m-6m-7m are all 83mm bore; 6m-7m have 91mm -stroke-.
 
the engine began as a sohc 2v 2L, 75x75mm.  it grew to 75x85, 80x85,
83x85, then 83x91, gaining dohc then 4v, and efi along the way.  also
along the way cam drive changed from chain to belt.
 
the top 7m-gte, dohc 4v efi turbo, was rated 265 hp, stock.  tuners
get much, much more than that - 500hp or more.
 
" The OHC drive adds some length, but these might not be too long.
 
these might also be an interesting repower for early xjs with blown
chevy 2.8s.  a jeep/toyota frankentranny should handle driveline
adaptation...
 
" But
" as I mentioned, width is a big issue. The Ford 240/250 fits and the
" size is a bit bigger too. The 200 should be at least the equivalent
" of the 196 in power, but has a bit more potential due to parts
" availability. 
 
nb. the ford 240 -is-not- related to the 250; it's a destroked 300.
 
cool idea - 200 with 12-port head and homemade 'rack o' ribs' intake
and scaled down efi from a 300.  2/3 flow injectors - no problem.  2/3
size tb with compatible tps from another ford - probable.  back it up
with a t96-o/d and really confuse folks!
