Can any one tell me how much this block is worth before I race it? It is complete with 13-1 comp 750 roller cam and GM d ports aluminum heads. I bought it and am not sure the value of the block being offered only in copo chevelle and camaro and tri power vet. I would be forever grateful for any info I get from this great site. Thanks Mike

Mike, what are the stamped numbers on the front pad of the block near the front passenger side of the block? The 512 block is pretty common unless it is stamped w/a COPO Chevelle or Camaro use code.

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.
