" What is the interest in the 252 other than History. The engine dates

wasn't there also a straight-8 version, or was that of the family it
replaced?

AFAIK the straight 8 used in the Nash was not related to the I-6 other
than they were both made by the same company. Where as the I-6, this 
one anyway morphed it's way through the ages until the late '60's in 
one form or another and a variety of sizes. , including flat head and 
over head valves. What is interesting to me is that the last versions 
had a relocated water pump in the front of the block.
I have a new water pump on a shelf that I bought based on the 
reputation that it is an AMC or Rambler water pump. But after needing 
a water pump this year and checking it closely it is nothing like the 
water pumps used on the 232/258 engine. 
This location was pretty much universal for most cars, but then again,
a lot of the '30's designs of engines were based on the size of engine 
compartment that they had to live in rather than whether they were 
a sound mechanical design or not.
Not that they were the only one's to play that game. The last of the 
Studebaker I-6's were overhead valve versions of the flat head and 
if I remember them correctly still had the side inspection plate
installed
that was removed to set the valve lifters as needed as a flat head.  
Proprietary engines powered a lot of '30's cars but in the Kaiser, they
still using a proprietary engine in 1954 when the went out of
production.
If I am not mistaken so did the Checker through the '50's some 
where. A part of what I find interesting about that era is the number 
of manufacturers that used the GM hydramatic  at that time. It kinda 
makes me wonder just how universal that transmission was in it's 
applications. 
The MOPAR slant -6 replaced the old flat head which I think was 
first designed for the Plymouth when it came out. Or close to that 
time anyway and was used up until 1959 in MOPAR cars and after
in industrial applications, fork lifts etc. That engine as I remember 
form high school era was prone to throwing connecting rods all over 
road if pushed hard. The biggest problem at that time was again,
more paved roads, heavier cars and faster cruising speeds. In the 
40's and 50's it was two different blocks and four different sizes.
