[QUOTE=jayd;432087]I've got a SB with a Code of V0202USA which should be a 1983 out of a C20 - 3500 pickup. The casting number 14093638 shows it to be 1986-94.

The heads have center bolt valve covers and it has a roller cam with stamped roller rockers. Did GM ever put roller rockers in roller cam engines that came in passenger cars and pickups? It was in a junk 1989 pickup but was not the original engine.

Is there any other way to identify what year and application this block is?


Jay..............see where you are asking about rollers rockers??.We'er saying GM didn't build them that way.Come on guy.Com down.We are just trying to help here and answer what was written.

I wouldn't worry about the numbers matching.The bottom line number is the rear casting number.That is the best I can do for you.
