| RE: 428: Could it be original? Please help. |

One thing right up front, I've never seen a 428 block with a C5AE casting. Now note that is what I've "seen". Every 428 block I've l've looked at had a C6## casting or later, i.e., C7##, C8##(You're getting into Cobra Jet stuff with the C8##/later castings).
Like you and giacamo, I'm not a purist by any means. You may have a very good block but you need to have it sonic tested/mapped to know whether it can handle an overbore beyond the current 4.13 you state it has.
As for the C6-R heads with the dual bolt patterns, they're likely to be '66 Fairlane GT heads and the -S- intake could be from any 390-428 standard 4V in '66. But it too may have come with the heads and been from the same F'lane GT donor. All the 3990GT engine had over a standard 390-4V was a nice mild performance oriented cam, C6OZ-B, and a Holley 600 CFM center pivot float.
