It's not on their web site, yet, but PS' FB page has some recent posts on their new King Cobra 4150 series. Think of it as a cross between a big venturi 4150 and an SV-1, where it still has 4 dedicated venturi, but uses spray bars instead of traditional boosters.

Not exactly unique, considering there have been other "spray bar" carb configs in the past. Still, interesting to check out and they're claiming "near Dominator" power for certain applications.
