It's actually a Northwest Speed Co. intake. I don't think they're made any more. Fesler is right, it's hard to find performance parts for these parts and when you do, they are not cheap. Ours has the adjustable roller rocker conversion, gear reduction mini starter, and a custom Poston cam but other than that, the short block is pretty much stock. The heads have mild port work and SS valves. MSD makes a nice distributor for them also. They can be built to make some power, a lot of drag racers ran nailheads back in the day. but I think that was because the didn't have anything better to use
