also, demon carbs are wet flowed so the flow more than they are rated, I can tell you I have a 408 stroker with big heads and a cust hyd roller, I went and bought a custom pro-systems 950hp, my 650 vs speed demon un touched starts easier, idles cleaner and better, has way better throttle response and low end the power is about the same except the PS hits harder and a hair more top end but overall I like the demon better and mine is a reman I bought off ebay for under 300.00 my prosystems cost over 700.00........its for sale by the way......30 miles on it!
