I pulled my heads in order to do some porting work and I see that the pistons tops are stamped "1941PX .030" . This engine was rebuilt in '94. Which manufacturer uses this number designation?

The pistons that you have are some old(93 or older) Sealed Power forged pistons. They are identical to the TRW L2125F pistons which are discontinued. They are just forged versions of the stock flat top pistons.

Thanks so much Joel.
This engine was assembled about 9 years ago when I was in the middle of relocating my family, job change, etc. (an 800 mile move). I lost track of what was happening and so I'm currenlty in discovery mode. For example, I've discovered that the head milling which was supposed to have happened didn't. These forged pistons are great news but also a surprise. When I spec'd out the engine in the early 90's, I had no plans for supercharging. I'll be checking out the cam lift once I get the heads reassembled and attached.
Again thanks for the info.
