Inliners International Forums General Discussion Engines boring out a 250

I called KB Pistons today. The Silvolite pistons offered for the Chevrolet 250 are standard aluminum alloy cast pistons. They are not hypereutectic aluminum (silicon 16 - 18%).

Could we get together with the Pontiac 250 OHC and Chevrolet 307 owners and order a single run of hypereutectic pistons in one bore size, say 0.040" over? Flat top pistons, no top edge chamfer, with valve reliefs for either the Pontiac 250 OHC or the Chevrolet 307.
