What's your mileage?

I find wind is my biggest hindrance to good mileage.

Mine is a 1965 C-10 with the following:

283 CID Engine
Holley 4360 Economaster 4-barrel Carb
ME Wagner Dual-flow PCV Valve with a custom designed catch can system
Headers
Dual exhaust with X-pipe
SM 420 Transmission
3.08 rear end
29" tires

Also, I use ethanol free gasoline exclusively. I also use AMSOIL synthetic oil and their oil and air filters.

How do you like the Economaster carb? I've got one sitting on the shelf waiting to be used on something. Sounds like a good setup with the 283 for sure!
