Small block suffix code

[SuperNovaSS]

I just picked up a 69 Vette with a early 327 in it. The suffix code is OS. I can't find it in any books or websites. Can anyone help with this one?


Thanks,

Jason

Jason, what is the casting number?

[JChlupsa]

Whats the complete code? I show a simple "S" for a 62, 63 & 64 327/250 HP Comp ratio of 10.5:1 with a 4 brrl carb and powerglide
---------------
ONLY "OS" i can find is for a 6 cylinder Chevy II engine

The S is the only code I could come up with also. It is a 62-65 327 casting number. Must be the base S code.
