The facts:
69 GTO
Matching numbers 400 with Comp Camps 260 Magnum (212, 212 at 50, 440/440 lift), Q-jet, ram air exhaust manifolds, 2.5" exhaust system, stock distributor with Pertronix
Turbo 400, Holeshot 2000 converter
3.55 gears
How can I get better than the 10 mpg or so I get? I may switch the gears to 3.08. Anything else I could do?
