Can anyone refer me to a web-site that will interperet some block casting numbers and tell me what I've got?
Was just given a Small block chevy, want to know what size it is. has 010 cast into the side, and on the rear of the block, it has a 42 cast in
Thanx,

Thanx. very informative. this block is a "very desirable" block due to increased Nickel and tin in the casting. It's a 350 2bolt main. looks like we have a winner.
