Were there any Non-SS big block Chevelles in 1970? I'm under the impression that all big blocks were SS. Is there a # on the block that corresponds with the VIN plate that would certify the numbers matching issue. Thereby proving it to be a real SS without any buildsheet? I know people have restamped blocks but lets just assume that isn't the case. A buddy of mine says there is no such thing as a # on the block to match the VIN and I thought there was. I know 1970 is one of the most cloned ever but I would like to one day own a real deal SS and need some way to verify its legit without a build sheet.
