I've got a 64 Skylark w/ a 2bbl, and I recently acquired a factory aluminum 4bbl intake. What size carb will give me optimum performance with the 300ci V-8?
http://www.buicks.net/shop/reference/carb_cfm.htm what is the maximum rpm you intend to run? 500cfm would pretty much take you out to 6000rpm ... and you can get that in a 2v Holley. i definitely don't think i'd go over 600cfm unless you've rebuilt and blueprinted/balanced the motor and intend to run it +7000rpm or you're running forced induction. 4v Edelbrocks; Edelbrock is based on the Carter AFB isn't it? http://www.edelbrock.com/automotive_new/mc/carbs_acc/pdf/carb_app_chart.pdf http://www.holley.com/types/2_Bbl_Keith_Dorton_Series.asp http://www.holley.com/types/Two_Barrel_Street.asp
