Just got home from a 250 mile ride with my 66 C-1000.It has 305E with a Powerglide and Dana44 with 3:07 gears. I have a 500 Holley on it with Pertronix ignition,plenty of advance and the plugs look perfect. Unleaded gas with No alcohol. 11.5 MPG,what do you think,is that about what I should expect? Thanks, Dave
