the 163 was the '68 up pass car 396-427 intake, I don't believe with a Corveyye application, but lots of Chevelles, Camaro's and others with SHP Bigblock engines. I'm not familiar with the other number.

Yup. It was used on the GM #366250 crate "LS-6". However, it was never used on any PRODUCTION LS-6, Corvette or Chevelle. The current version of the manifold is no longer cast by Winters Foundry and, so, the "snowflake" casting symbol is no more.

GM #6269318 was, indeed, a big block, rectangular port, aluminum manifold. It is similar to the 3933163. However, it was either a SERVICE-only or SERVICE and Marine manifold. It was never used on any PRODUCTION Chevrolet big block engine. I don't know how it differs from the 3933163.
