hi fellas im in the process of buying a 84 c10 stepside 305ci, 3sp automatic,that i am slowly going to fix up while at school at NTI. i am looking to buy a new carburetor, intake manifold and headers for the truck before i have to drive to north carolina for school. i was looking at the 600 cfm summit carb vac. secondaries and vac. choke. will 600 do it for a stock 305? and the intake im thinking a weind action plus manifold will work and the hedman street tork step headers with flowmasters. i figure this will a be a decent combo to get good mpg's from the little 305. any ideas??
