Campbell Enterprises says they are out as does Mancini and most other places I've checked. What I want is the Speed Pro L2315F40 but that number is going to be replaced with an L2315NF which they haven't started production on. If I could find just one set I'd be in business but I don't know where else to look. Any ideas? I don't want any cast pistons, just forged. And I don't really want to pay Diamond the extra $300 to build me a set if possible. 1968 Charger 383/2bbl/4spd (1 of 74) 1994 Dakota Sport 3.9L/AT/2WD 2003 Durango SLT 4.7L/AT/4X4 Yes, all Dodges and nothing else

No, not zero deck.

If you are decking the block at all I would pony up for the diamonds , get them in the CH you want since you are at semi custom anyway and they will do 2 minor tweaks for the same upcharge , plus is it's much lighter, better selection of rings and comes machined for spirolocks incase you want to buy eagle rods which are floating pin. I'm in your boat , I need a .040 over now and Diamond is my only choice .
