Default Re: Flathead Gas Mileage

Sounds like my 396 Camaro with 4.11s.

I would say shitty carbs or bad distributor.

If gas isn't running out the pipes, you have a high gear that you use and your eyes don't burn when driving it I would get a good distributor in it. At this point you will have a tough time making it worse. A good distributor is a good update even if it isn't the problem.

What do the spark plugs look like ?

A good pair of carbs is a little more spendy but it may come to that. Multiple carb setups are great but they can easily give these results. I guess if you have a buddy that will borrow you a single carb manifold with a proven good carb you would know right away.
