My 292 TBird has the usual upgrades, "G" heads, Isky cam, 57 distributor, "D" code 4V Iron Intake, Holley 0-1848 465 cfm vacumn secondary 4 barrel, 4.11 gears and O/D. I'm thinking about trying a 600 CFM Holley double pumper for better street performance. Is this a better option or am I going backwards?
