Its a 63 Impala 409/340 block...The pad reads T0404QC, so the C part of it date jives with assembly date..Why are the following characters letters and not numbers? http://www.yenko.net/ubbthreads/images/graemlins/confused.gif

63-65 409 blocks have the casting dates on the far right side of the bell housing flange below the deck. Is this what you are showing?

Hi, CFD ( central foundry division) is where the block was cast.

The numbers on the other side of the bell housing flange will be a Julian date, meaning the numerical day of the year.

Thanks guys!

I guess I was looking in the wrong spot for the date..

I was just trying to go through all the numbers on an Impala SS409 for a customer and was stumped as I thought that was the correct location for the casting date.....

I think the new meaning of CFD should be "Can't Find Date". No offense to anybody, it's just that a lot of my friends and people selling these blocks over the years had a hard time finding the casting date on these blocks.
