V0414TYY - Flint, April 14th, TYY 1975 350ci/165hp/4bbl/conv.cab. It's a 1975 truck engine.

157510721 - the first 5 indicates 1975, after that is the VIN sequence for which truck in went in to originally.

Hi,
LS 9
Since it was headed for a truck… maybe 4 bolt main bearings?
Regards,
Alan

Removing the oil pan will tell all!
