as the post heading says - is anyone using one of these yet for street/strip.
they do seem priced right and i think my 825 mighty demon might be in for a change as it has become more niggley to tune.
Specifically i am asking about the 850 ,#8084 , model.seems to be as big as a hp1000
copied from Holley :

Important note: Venturi sizes vary considerably from previous Holley i.e new 950CFM is larger than the previous 1000CFM, the new
850CFM is larger than the old 950CFM etc.
