73 340 SB Rebuild, Need Help Selecting Parts

Is your intake the performer 318/360? If so, a performer rpm would be a better choice, or even a old edelbrock ld340 if you can find one. I would not use that particular piston in your case, I would use a Keith black KB243, lighter, tighter fit in bore..... otherwise everything else looks ok....Aluminum heads are a plus, get compression in the 10.5 or so range...custom grind solid flat tapped would be nice also
