Rearranging the garage...came across an old flywheel which I think somewhere along the line was in my 64 Chevy...Casting no. 3729004...has a yellow ink stamping number of 3739423 and a casting date code of A45...looked at some old forums with a lot of info but cast date baffles me...is it Jan 4 1955 or Jan 4 1965? Any ID help would be appreciated...Billu38

3729004 is a 1955-59 Chevy V-8 flywheel
