350 turns out to be a 327.....

[1968 C-10Cowboy]

I just looked up the casting #'s on my heads and they turned out to be 327 heads 60cc. Is this good or bad?? Now Im curious as to what the block #'s are. It sure has a big cam in it and good power...but hmmmmm. I may have been had by this guy who sold it to me. It's definately not stock and it has recently been rebuilt cause you can still see the paint on the block. Maybe 350 with 327 heads??
