Denny thank you again also . I did find the info here doing a google . This site had the most description also of any i read last night . Most where bits and pieces .


FFR it did to me also but the wire brush took good care of the S LOL. Also a few spider webs around there . The number does show up more for a 428 catagory and if its thicker that will be good . Read alot where the 390 is a bullit proof block mostly in stock form and a clean up bore may be required . I also read where the bore on this block is what determined its CI and was capable of being a 428. Ford did alot of things that a book will not have straight up info on . Its the guy with experience in the garage from the time who has all the true facts that are not on pages.
