Ive got a set of 12A irons with a full bridge port that are taking up space in my garage, so Im looking to sell them. Ill let the pictures do the talking on the porting.











$350 for all 3 irons, plus shipping.

Where would the power band be with that sort of porting? What sort of power are these ports capable of?

240-280 hp (flywheel) at somewhere north of 9k rpm. Its very dependent on the rest of the setup though.
