I have a 428 or 410 i believe just the block, it has C6ME on it and date code looks like 6A22 there is a V above the 6 and to the left also, block has 39 or 36 and 22 over 352 ON DIFFERENT PARTS OF THE BLOCK also.....I didn't see an A or C scratch anywhere, but the block looks like it has been hot tanked, and was getting ready to be put together.......Need some help with the ID,is it a 428 OR 410 or did they make another block with C6ME, measures 4 1/16 across IF I MEASURED CORRECTLY, is there another way to check the stroke and bore with no crankshaft or ? ? ? ..One more question what kind of value do these have if any....I can send pics to anyone that wants to see it, i took alot of pics...

Thanks for the help...
