Hey Now, Now Each To There Own With Opinions Of Course, But Ive Used Rocherster, Edelbrock And Holley. I Find That Most People Use Rocherster And Edelbrock Carbs Because There So Easy To Set Up. I Preffer The Holley. Even Thou It Takes Longer And Is More Complicated To Set Up, They Run 10 Times Better When Tuned Correctly. If You Spend The Time Youll Notice An Amazing Difference Between Holley And The Others. Also, Holleys Tech Line And Online Help (they Email Back And Forth With You) Is The Best You Can Get. They Actuall Ran Me Throu Tuning A Dominator While On The Phone With Them. Cant Beat That!!
