Re: Block Number
You will find a large number upside down:
627=...305
638=...350
880=...350 trk.
These are the last three numbers of the block casting.
14093627...305...87-94...2...Roller or flat tappet cam, one-piece rear seal
14093638...350...87-95...2 or 4...Roller or flat tappet cam, one-piece rear seal
10243880...350...95-00...2 or 4...Vortec truck, Gen.I crate motors and "ZZ4", roller cam, one piece rear seal
That should help you.
