Small Block Intake

I bought a Trickflow 750 dp ( Quick Fuel SS-750 SS-Series Carburetor 750CFM) to replace my 670 Street Avenger. It's got all the bells and whistles and I have no idea what most of them do! If I had it to do again I'd go Brawler 750 dp (Brawler BR-67213 750 CFM Brawler Street Carburetor Mechanical Secondary) and save a few bucks.
