That would be about a 347-348 Cu In motor. This would be called by many as a good old 350/5.7. McMaster Carr and others have metric bolts. Ace hardware has metric bolts. Dealer has them. ARP has them. Jeggs, Summit, RockAuto. Be sure you know what size/pitch/length you have. Most other SBC have 7/16-20 as you say. Quickest place: O'Reilly's has M11 X 1.5 under 1998 Corvette. Part No. 330-2802.
I don't know what motor you have or what bolts, so the above is just food for thought. If you ask for 327 bolts you will get 7/16-20.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
