I'm assuming you guys are talking about 400/455 applications. Last I talked to KB, a 389 piston was still in the design stage. Anybody heard if they are really going to produce one? If they would make a dished 389 piston I would buy 2 sets and send them a Christmas card every year.

Neil,

I believe they offer the 400 pistons in "Standard" bore size. You can use them if you bore the 389 to 4.12"
