" Hi all, in a recent post there was mention of AMCs dealings with GM in 
" regard to Buick V6. (and also Mazda rotary)
" Does any one know what AMC did in the way of development of the V6. I 
" understand when GM took it back it was different. The oil pump looks very 
" AMCish for one. And I believe the engine grew a few cubes. Some reference I 
" have seen states the balance shaft in Mitsubishi 4s in under licence to 
" Chrysler. So did AMC put the balance shaft in? I don't know if the 225 V6 
" had the balance shaft.

no, to both cubes and balance shaft.  i've heard kaiser used a very
heavy flywheel and that their v6 will idle smoothly down to 200rpm.

don't have data handy, but i believe the front cover is also
unchanged.

amc did nothing in development; they sold the tooling back to gm when
they bought kaiser.

a brief history of the v6:

1. 215 aluminum v8 '61-3, rover '66?-'00?
2a. iron and aluminum 196 v6; rare, dates unknown
2. conversion to iron, 300 v8 / 225 v6
	there were a few aluminum 225s too, largely experimental iirc.
3. 340 v8 '67?
4. 350 v8 '68-'81
5. 231 v6 '75?-
6. 252 v6

etc.  up until a late[?]-'80s redesign, i believe all these engines
used the same front cover, oil pump, timing set, etc.

the 225 was sold to kaiser ~'65 when gm mandated chevy sixes across
the corp.  yup, buick and olds; the poncho ohc was a redesigned chev.
the 225/300 and 340 share pistons.  the 350 was a slightly overbored
340.  it was natural buick would overbore the 225 to 231 when they
took it back, so it could use 350 slugs.

the buick is/was gm's lightest, smallest 350.  considering all the
effort they put into v6 speed parts i've always thought it a shame
none [like the block and heads] were ever made in v8 versions.
politics, i suppose.
