I did a tune up....plugs, wires, set timing a bit more than recommended (doesn't ping)...........in my 77 Dodge van with a 360 and went from 12 to 15 on the highway...................Around town, it's going to suck the gas anyways.

poncho62 08-14-2005 07:50 PM

BTW...gas here today was $1.02 /litre................thats $4 per American gallon.

These gas prices are something else! I never thought that I would see hot rodders concerned with gas mileage. Its always been more horsepower, LOL. What gripes me is $ 13 to fill up the gas can for the friggin lawnmower!

spinn 08-14-2005 07:54 PM

were all screwed . gas is gonna go higher.
