Thanks, I may have found it to be 7109. I forgot to check Jolly's known numbers and low and behold he has it and so does O'Reilly's listed for a 66 Olds 330 V8? Came into it sideways. I am going to check the given sizes against the one I found on the floor: ID, OD thkness. Will advise. Thank you for the reply.
