Hey everybody! I have a question about mpg. My '67 coupe has a 289 that has been bored over .030 by a PO. The carb is an older Holley 4160 series that has been rebuilt. My fuel pump is new, and is made for a 4 bbl carb, which I have. My plugs and wires are in great shape, I have a Pertronix ignitor and 40,000 volt coil, and I run an 11" K&N open filter. My car burns a lot of oil, and puts out light gray smoke most of the time that it is running (maybe a mixture of oil blow-by and incompletely burnt fuel?). My question, finally (!), is this, what can I do to increase my mpg? My car is a daily driver (I can't stand to drive anything else) and gets about 10 mpg in city driving, and 12-13 mpg on the highway. I use 87 octane gas. Is this about as good as I can expect, or can some adjustments be made that will help increase the mpg? Thanks for your help!
