Re: 512 block copo camaro 4 bolt 060 overbore
On the rear of the block near where you found the "512" casting number should be another set of numbers w/a letter for example: K178. If it is an older block it may be located on the side of the block. These are RASIED letters and numbers. On the front of the block on the passenger side is a machined pad right where the cylinder head bolts on. On this pad will be a series of STAMPED letter and numbers, for example TO116CRV. Post what you find and someone will let you know what you have an an approximate value. The fact it is 0.060 over decreases the value.
