C2 Assembly Question

[Dave C.]

Were blocks pulled in numerical order or random. In other words, if I have a car, lets say a Jan 15th birthday, would my block date be earlier than a Jan 16th birthday but after a Jan 14th birthday?

It is much more random than that. If you look at surveys, blocks with the same date can span several thousand serial numbers. Take a look at the survey results in Nolands book. There are several BBs with a casting date of C77. They range in serial numbers from 14620 to 17546.

Dave,

There are two engine dates to be concerned with. The first is the block casting date which is cast into the block and are raised alpha-numeric characters. Then there is the engine assembly date which is stamped into the front pad of the block and are depressed alpha-numeric characters.

Generally the block cast date is a week to a few months earlier than the car's birth date. The engine assembly date stamp is generally a few days to a few weeks before the car's birth date.

Exceptions regularly occur, never say never.

Hope this helps.

Re: C2 Assembly Question

My L-79 engine was built on July 2nd and the car was built on July 6th. It's a late '67, so I guess maybe the factory was getting ready to close down the '67 operation to gear up for the '68 run.
