I just bought an 86 it has a 305, TH350, 2.73 gears. Needs a cam (Bad Lobe) so I ordered the sum-k1102 262/ 272, Lift .420/ .442. I going to run either a performer or performer air-gap intake. Which carburetor would be the best for fuel economy the Holley 570cfm Street Avenger Carb. or the Edelbrock 1406 600cfm Performer Carb. I would like to get atleast 15mpg. This will be all that is done to the truck. When I get some extra $$ I will add duals with some flowmasters.
