One of the guys at work had a Holley Street Avenger 570 that he lets me borrow to try in place of the Edelbrock 600 and holy cow what a difference.. My 327 matched with the new 3:73 gears and that Avenger Carb woke the Camaro up! Smoke show in first and a chirp shifting to second Exactly what I was looking for!! I was amazed at what a 570 cfm did to my low end power. Now I need to sell the Edelbrock Carb and find a Holley 570 Street avenger before the Rod Run down here in Long Beach. Anyone have one for sale or need a 600 edelbrock??
