casting numbers

I have a 1967 roadster with what appears to be a 350 cubic inch engine. I have been looking for a 327 block to replace the 350 with, now for the rub was the casting number 3914678 ever used in 1967 in a corvette. Noland Adams was not definitive one way of the other, thanks for the help Tom

you are looking for a 3892657 or a 3903352 that might have been used late in production. the block you found was used from 1968-1979. for a 302, 327, and 350. used in both cars and trucks

No, it wasn't - it was only used in Corvettes in 1968. You need a 3892657 block; the usage of a 3903352 has never been documented or verified, and will result in a total 350-point deduction in judging.

The Spec Guide was last printed six years ago, and the 3352 block is noted there as "unverified"; that's still true, and is why it doesn't appear at all in the '67 Judging Guide. The 3352 was only used in passenger cars.
