Saw this article on Hot Rod today. All aluminum Pontiac with lots of good parts including dry sump and very fancy headers, Cam is fairly small and the header shape is unusual so I'm guessing that this is a street engine in some sort of weird vehicle? The article doesn't say what it is going into but the cam is too small for drag racing. I suppose it could be some sort of road race car. The small cam, dry sump and weird headers could all work in a road race vehicle.
