Re: Potential 327 overbore questions

You could possibly gain more power via a slight increase in compression ratio, as the standard ratio is very low (at around low 7's from memory) and suited for use with the types of fuel available back then. Higher compression perhaps could be achieved by taking a little off the cylinder head and running higher octane fuel. It's a fairly small ROI either way, given the great torque and tractability of the 327's.

I'm not aware of how much can be 'safely' taken off the cylinder head of a 327 . . . See what others with more knowledge of these engines say about that.
