Block Identification Number Help

Hey I have just Recieved a V-8 350 Block and I want to know what year it was made and how much horsepower it has and information like that. This is an old engine made in around 1960-1970 around there. There is nothin on the intake manifold so there is no pollution stuff AT ALL. It is VERY hard to read the Identification Number But it is ethier 3370016 K2 or 3570016 K2. The First two numbers are hard to read but im sure it is one of these. This is a GM Motor. Can anybody help me find the specifications of this engine or give me a site. This would be greatly appreciated.

Try this website. Their name is american association of casting numbers :) They have darn near everything.

You have to pay to go on there site to view the numbers. I was looking for some free site which has numbers. I have googled it pretty good and still can't find "T4U" for a engine suffix code. Im starting to think they messed up the number or something. If anybody has found anything about it can you please post it. thx curtis for your post anyway.

Oops, didn't realize they were a pay site. :) I couldn't find anything on the T4U either. Could be a date code of some sort
