should'nt that prefix start with the letter 'c' ? can't find that combo in my book.

Well did some diggin around and I also went and got the casting # of the block. The casting number was 473478 which looked funny at first but when I got home I found it on the net and its a tall deck 427 truck block. Thanks for the help..
