heavy duty 350 M block engine, crankshaft ?

[R72K5]

i know where an old 69-79 2bbl heavy duty M block 350 truck engine is at, or at least hopefully is stil there, 50 or 60 series truck engine,
i would think the crank in these would be forged or steel

and i wonder what pistons were used in these

i already got the bellhousing adapter plate and some other things from it including the 4 groove crank pulley, etc.

the bellhousing plate is a stamped steel plate that allows use of the massive CH465 bellhousing, it is huge, way bigger than any 1 ton and smaller bellhousing, the flywheel has to be at least 16" across if not more

i wonder about that bottom end,


hmm

Check the parting line on the crank.

The cranks in any c50 is a forged steel crank with ultra low compression. I have found this out by working a few the last two weekends. The pistons are dish(like looking into a bucket dished)but they are thick and normally use 4 rings instead of the standard 3 rings. Hope this helped out some.
