Re: [AMC-list] Last 401

[Glen Hoag <hoag@xxxxxx>]

Just to muddy the waters a bit more, apart from the service 
replacements of AMC 401s with smaller AMC engines, IH trucks were 
offered with a 304 V-8.  This is *not* an AMC 304; it's part of the 
IH 304/345/392 family of engines.  (Not that anyone goes looking for 
an AMC 304 all that often.)

When you find an AMC engine in a 73-74 IH, it wouldn't hurt to check 
for the "401" cast into the side of the block before getting too 
excited.  The Binder community has a quick way to distinguish the AMC 
and IH engines; check the shape of the thermostat housing.  If it's 
round, it's an AMC.
