OK to start I apologize I was "told" it was a corvette block. I did not pull the engine yrs ago I bought it off of my wife's uncle.
And the date code on the pad where most Chevy blocks are stamped there are no numbers. I'm thinking that the block might have been milled or shaved, not sure which its called on the block. I was told there was minimal valve clearance between the heads it had but they were removed before i bought it.
Now the numbers on the back that are to the right of the casting numbers are "L1555" which I'm guessing is December 15, 1955. On the front the numbers are "F62663" these numbers are right under where the front of the intake would be. These are directly above the timing chain cover and are upside down. I'm trying to post these pica forgive me I'm on mobile. And if anyone wants to give me info even if they are not interested is appreciated.
Please no rude comments. I understand we all have our certain intrests in cars and I don't know the whole casting/Suffix code ordeal.
