Welcome and glad to have you here! The mods limit posting of pics to the new guys because of spammers. Once they see your genuine, you'll be all set there.

My memory says only the very early 396 blocks were actually a 396. Cheby went to the 402 but kept the badges at 396. So maybe you have a .030 over 402? Pat & Jerry are the guys who can help you through the maze on this one. They'll be along and chime in.

If you need help in getting pics up. Flip me them in an e-mail and I'll toss'em up for you.
