Well, I was able to get hold of a pair of 427s from a 1960s Chris Craft. I don't know exactly what numbers I need for identification of what I have, but the cast number on the side of both of them reads C5AE-H. I have read different threads about the blocks being casts as sideoilers but not drilled. How do I know (where will I see the drilled out passages) what it is? Both are in EXCELLENT condition (pistons look great) but I would like to be certain of what I have. THANX!!!
