273 vs 318

Whatca talken a boot ? LOL! Cudaguy6, yeah 650 is pushing it for a mild combo. Id be perfect for steep gears & healthy camshaft. I just (today) got my quick fuel HR 450 cfm mech secondary carb dialed in & the throttle response is sweet! & pulls harder rite into the rev limiter a whole lot better/smoother that the old 500 edelbrock ever did even dialed in! Easy to over carb thease little guys.
