I have a cast iron intake manifold with the casting numbers 380059 . I cant find this number in any of my reference materials , any ideas ? It is a small block olds with the Carter carb bolt pattern,thanks. BOB

 

A square bore intake for an SBO would have to be from a 1964-65 330. The carb was a Rochester 4GC. The 380xxx casting numbers are consistent with the 1964 model year, so I'm going with that - a 1964 330 intake.

 

Thanks for the info , where did you find the casting numbers info ? BOB

 

Well, from the various lists of intake casting numbers that are around, I see that 381920 is from a 1965 330 and the numbers are generally associated with model years (390327 is a 1966 casting, for example), so I'm guessing that 380059 is a 1964. It can't be any earlier than that, since 64 was the first year for the SBO.

 

There are a few on the internet for sale as well. One is listed as a '64 442 intake, but I would imagine it would be for any '64 330 engine with the 4 bbl option.
