69 SMALL BLOCK QUESTIONS?

[incom5633]

 IN RERERANCE TO: 386, 618, 388, 010, BLOCKS.
WERE ALL 69SS SMALL BLOCK ENGINES CAST AND ASSEMBLED IN TONOWANDA. I KNOW Z28 BLOCKS WERE STAMPED AT THE FLINT PLANT. BUT IT SEEMS THAT IVE NEVER SEEN A FLINT STAMPED SS SMALL BLOCK. ALSO WERE ANY OF THESE BLOCKS LISTED CAST AT BOTH PLANTS.

All four of those blocks (especially the 010) were VERY common, and were used in virtually all passenger cars and trucks for many years; all were cast at both Flint and Tonawanda in high volume. Can't answer the SS/L-48 question specifically, but 350/300hp engines were made by the millions at both plants, and I can't imagine Tonawanda being the sole source for Camaro L-48 engines. Flint was the sole source for 302's and all Corvette small-blocks, but those were unique low-volume applications.
