I was just looking over the KB site and found a forged piston KB102 that looks like what I need for my new 383 I'm putting together, just wondering if anyone had used these yet, what I like about them is the running clearance of only .0015 min. some the specs are as follows:

** 3-WAY PIN OILING
** TEMPERATURE SUPPRESSING RADIUS AT THE VALVE RELIEF INTERSECTION
** MODIFIED ANTI-DETONATION GROOVES

** DIAMOND MACHINED
** HYPO 18 ALLOY

I have not run those but KB makes a good product. I will be turning over my new 383 with the 12cc dish hypers this weekend and dont anticipate having any problems, I will be making ~450hp NA .
