Re: [Amc-list] Nashcan sixes

[Frank Swygert <farna@xxxxxxx>]

The big old OHV sixes are not pretty! Intake built into the head like 
the 196 OHV, and even worse the exhaust "manifold" is a pipe clamped to 
the block like the 196 L-head! It just clamps on the angled surface 
under the intake. At least the 252.6 is that way, you'd have to go back 
to 51 to find a 234.8 (52 in the Nash-Healey only), and I'm pretty sure 
it's that way also. The 234.8 didn't have a rear seal -- it had a close 
fit and shallow "backwards" threads made onto the rear to keep oil in 
the block. LOW rpm engines, but good torque. The 52 "LeMans" six put out 
140 hp @ 4000rpm, and I doubt it would run over 4500. The 234.8 as used 
in the N-H only produced 125 hp. Both of those had twin side-draft 
Carter YFs.

The Statesman engine was the old L-head, 172.6 41-49 600/Ambassador 600, 
184 50-52 Statesman, 195.6 53-56 Statesman.

Crower (the cam company founder) built a big Nash Straight Eight for a 
Bonneville car back in the 80s. I don't recall any details such as what 
year engine it was, but had to be 42 or earlier -- no I-8s after WWII 
for Nash. I do recall it was an OHV model, but all the Nash I-8s were. 
First one was in 1930. Seems that I recall it was a Twin-Ignition I-8, 
but not too sure on that.

Of course any engine can be highly modified to do more than it was 
intended, such as the Crower/Nash I-8. I know he used special pistons 
and rods in it, I think the only thing Nash was the block, head, and 
crank. Lots of hand machining done.

Anyone here know about the Nash sixes? The latest Hemmings Classic has 
an Ambassador in it, and it mentions the motor (photo is similar to the 
195.6 OHV we all (well, very few of us) love. It implies that there was 
a big, strong Ambassador six, and a lighter, presumably cheaper, six for 
the Statesman. I assume AMC got the light six. Anyone know off hand 
what's different between the two? The Nash CLub people would know, but 
right now my car time is in 30 minute chunks on the internet (and 
sloooowly dropping off parts to be hot tanked and blasted for later 
build...I'm still hot to build a hot, light, nash six...)
