As an aside, all the 460 builds I see use aftermarket pistons, what's up with the factory ones?
You are aware that the stock pistons in most cases are 30+ year old cast assembly line quality?
Not exactly ideal for making reliable power. Especially since you're most likely going to bore at least .030 over in the rebuild.
TRW forged are about the bottom of the barrel for these builds. The draw back on those is they are pretty heavy, but they can handle a lot of abuse if you don't go too wild on stroke or keep the RPM down. If you're going stroker, the pin height changes and you're going to use a new piston anyway, along with Ford/Chevy/Pontiac 6.7 or 6.8" rods. The exception is the SVO/Motorsport cranks that still utilize the Ford 2.5" rod journals and 6.605" stock rod sizes, but they still need a new pin height.
