Mr. Norms GSS 340

I, too have one of these blower setups. Hope to use it someday on a 340 I have in my 67 Cudavert. I'm curious, how do you know it is unit #60?

Something else I have is a Jan. 72 copy of Super Stock & Drag Illustrated. On the cover is a 72 Demon GSS. There is a writeup in there about the buildup on the car. The car on the cover is the development car. In the story they mention planning to make 250 of them but I suspect that didn't happen.

Supposedly the only mods to the carb was drilling out the jets a few thousands. They also put in a Milodon high volume oil pump and aluminum valve spring retainers. And I think a pinion snubber. Also a higher pressure mechanical fuel pump with a pressure regular.

Also there is an ad in the magazine from Mr. Norms for one of these cars, $3695 plus tax! I tried calling Mr. Norms years ago about it and they weren't much help. I asked them how many they made and the response was maybe 100?
