GTO Intake

[Ggracie]

I have a 66 gto with what I belive to be a 389. The problem is I belive the intake is from an earlier Pontiac. I can not find a casting # on the intake. There is what I belive to be a date code between the carb and the sending unit boss. It looks to be O274. Does this mean the intake was cast in 1964?

It is off of a Pontiac with a firing order of 18436572.

Ken - be nice, it was his first post! Ggracie - Welcome to the board. Ken is correct that you posted the firing order. Look for another 6 or 7 digit number cast on the intake and post that here, or if your (or your library) has a copy of Pete McCarthy's book, the casting numbers are listed.
