Recently purchased a '49 Chevy 3100 that has had the engine changed and I have been searching the forums for information. Believe the engine is a 1958-62 Chevy 235 but would like confirmation and a closer date if possible.

Block: casting #3769716 stamped on flat: F0409J
casting by starter: CON 3 D22 GM24

Head: drivers side casting # 3836848 GM-25
passenger side casting # B50 848/850

Most of those numbers lead me to think 1958-1962, but the valve covers are held on by two nuts. The valve covers are Wayne.
Any help would be appreciated as I am new to this.

Thanks,
Austin
