I was looking over the engine that I had pulled out of the crew cab a few minutes ago, and I decided to write down the serial numbers. The heads come up as being 427 side oilers?

The casting number for the heads are C8AEH. The blocks casting number is C6ME, and that comes up as a 330??? But that doesnt sound right to me Im probably excited over nothing, it will probably turn out to be a plain old 360

. Ive never hear of a 330 though I thought it was 332-428. Right?
