Mike,
The best way is by casting number. www.inliners.org has a pretty good
list, with links to several others (you sorta have to hover the mouse around
this page as the links aren't too clear). I have never failed to get a hit
on at least one of these listings, except on Canadian models. The listing at
www.inliners.org/becks/ also provides ID by engine number prefix, so there
is an alternate way to identify the engine, in case the casting number can't
be easily found.
There was an optional 235 for heavy trucks in '48. It was called the
"Victory Six" or "Hi-Torque" 235 and looks just like a 216. I know of at
least one confirmed instance where this engine was installed in a new 1/2
ton as a dealer upgrade. It was a dipper-crank oil slinger like the 216 of
the same era, introduced in 1941, first with babbit mains, upgraded to
inserts in 1948. All of these older type 235's used babbit rods. Very tough
old workhorse engines, they were often the basis for the Wayne 12-Port
racing engines of the late '40s. They differ in both bore and stroke from
the 216.
I have some early Inliners tech stuff that has some more detailed ID
methods, but you should be able to nail down your engine from the above
references. If not, let me know whatever numbers you come up with, and we'll
go from there.
