Alright, I just bought this short block assembly with 427 heads (C8ME-A), and when I took this to local engine shop, they measured the bore and told me this engine was NOT 428 due to the 4.05 cylinder bore and they thought the crank was incorrect because it was not a steel crank !!! The Engine Casting number is C7ME-A ........ should be a 428 according to my research and in books that I bought for reference. Is it possible, that this might have been a SERVICE BLOCK that was bored for 4.05" instead of 4.13" ??? How would a C7ME-A block have a 4.05 inch bore ??? I really need some help on this one, if anyone out there KNOWS for sure what we have here !!! I am located in Memphis,Tennessee area. Send me an e-mail, if possible ........... markcasillas1955@yahoo.com

You need to do research on any Ford FE blocks. The books that are out there are wrong and C7ME-A is a perfectly correct number for a 352, 360, 390, 410 or 428. The number will not tell you what it is as they all used the same outer molds so they all have the same numbers. This is true for most 1966-1972 FE engines. Hawkrod
