FE block code question
I have a 427 block (I think) that is a cross bolt block but the casting numbers aren't back by the starter, instead over the moter mounts. It reads "C3AE" then under that it reads "6015" with no letter after the part number. The freeze plugs are not screw in. The block is .040 overbore. Is that to much on a center oiler? The builder said he has seen them go to .060 but I thought .030 was about all you could do.
