0.125 over - ouch !
I know others have done it, but I'd be leary of buying a
block that is bored this much. Will the current bores fit
your pistons? If not, you'll have to bore even more?!
For almost $900.00 and possibly 8 sleeves, you're talking
big bucks here. I'd consider holding off until a more
suitable block presents itself.
