If you:
-Change to a smaller carb
-Change to EFI
-Change the diff. ratio
-Change the gearbox
-Change the cam
-Have a dyno tune
These options would help reduce fuel consumption, but would cost from a few hundred dollars to a few thousand dollars. If you spent that sort of cash, how long would it be before you showed a
net gain in $ ?
Just my opinion....but the biggest influence on fuel consumption is whose foot is on the accelerator
