Paul,
The 429/460 series engines are different and are of the 385 series. The first FE I had wasin a 1958 Ford Fairlane and it was a 332 Police Interceptor. I don't think it has anything to do with being a big block or small block.
Mike,
I had forgotten about the Ford/Engineering that was included, but I really don't think that one was the right one. Maybe we can find a contact in Ford that can actually tell us what it did mean. It seems that maybe Ron(CW) may have posted what it meant. If not, I am sure that he would be the best to find out from.
Ron
