which engine is going to get the best fuel mileage. (with good power)
I need to run 20 min. main with 1 stop
I run on midsize loamy track, descent traction (revalation raceway) s. cal, with many pro drivers
need bottom end power/ punch. but smooth and controllable.
i currently run a ceo modded c6 7mm venturi with 2045 pipe and 1351-192p header, alum clutch 1.0 spring rb #7 plug. All suggestions appreciated
