Tim,
Our shelf pistons used to be from Arias and Ross, and we still have some inventory of those.
We now have our own pistons, which are about 100 grams lighter than the other FE pistons we have had our hands on. Our forging die has all the extra material removed from underneath the piston crown, except where FE valve reliefs are (excluding Cammer of course).
We stock a wide variety pistons, or if you have a custom or unusual application, we can finish a set to your spec. Within reason, we can do whatever bore diameter, compression ratio, pin height and bore, and ring package you'd like. Minimum bore for our forgings is stock 427 (4.233").
These are not reboxed other-brand pistons. They are produced from our own forging die, made specifically for FE's.
We are the largest stocking dealer of FE products from Scat, so maybe we can put together a package deal for you on pistons, rods, crankshaft, and block. We could even turn it into a shortblock for you.
