hi,
I keep seeing eveyone talking about that vacuum secondaries are the best for the street and i was wondering what is the differance between that and the mechanical secondairies?
Im asking this because i have been trying to get my carb all set in and i have a 750cfm holley 4150hp carb, with mechanical secondaries and was wondering if there is any tricks or anything to make it better for the street. I just had the carb fully tuned and everything, but just wondering if it will ever run good on the streets.

thanx,
david
