Re: [AMC-List] Gen 1 to Gen 2 change over

[<francis.swygert@xxxxxxxxxxxxxxxxxx>]

There aren't many changes necessary. Early GEN-2 engines still used the
Borg Warner auto trans. Those have a separate bell housing, not cast as
part of the trans body. So it is simple enough to get a GEN-2 bell and
bolt a GEN-1 style trans to it, or just get the tailshaft housing from a
GEN-1 type trans -- the output shafts are the same, just the housing is
different. The engine mounts are in the correct location IIRC. One might
have to drill new holes for the mounts, but that's about it. 

I have always understood that there is a *possibility* that 290s were
substituted for 287s near the end of the 66 model run, but have never
seen any proof. The VIN on the 66 Ambo would tell if it came with a 290
or 287. But in all honesty, it's likely a later transplant. The 343
didn't appear until 1967, only the 290 was used in 66, and no 290s in
Ambassadors, at least not in 67 (I don't think the Ambo ever got a 290
or 304). If this were a 66 Classic or Marlin, then there is a
*possibility* it is the factory engine. The 327 remained in production
for at least another year (through 1967) since orders were coming in
from Kaiser Jeep and Gray Marine.

I have seen some information that late 66 model year cars came with the
Gen 2 engines.  Given the changes necessary to do that I doubt it would
have happened until the full model year update for the 67 line and the
elimination of the closed driveline.  Yet I see a 66 Ambo on EvilBay
with
a Gen 2 engine and have heard of 66 Marlins with the 290 (supposedly the
last 200 made).  I always attributed it to somebody not familiar with
AMC's mistaking what they had.  Anybody have the official word?  To add
even more confusion is the fact that AMC supplied the GEN1 327 to Jeep
through the 68 model year so they either used up old engines and kept
the
GEN1 in production for 2 years after they dropped it from their own
model
line.
