The cranks are at the machine shop. I=E2=80=99ll check when I get them =

Was hoping someone on the list might know.
Thanks,=20

Don,

The exact alloy number may be cast into the crank somewhere so if you =
have the crank out of the engine, look for a number that starts with =
?EN?.  Problem is, you will have to look up what that is compared to US =
nomenclature. Also, contrary to what I had always assumed, the TR =
motor?s crank is steel, not iron, and perhaps the Spit crank is as well.
