Hey, Doc, I know you keep bragging about your 12 sec car that gets great MPGs with 2.76 gears. have you ever considered that half the argument is in all the glass parts on the car? your car weighs significantly LESS than the average A-body.

I think weight has more to do with MPGs than engine size or gear ratio. I'll go back to the Dakota's to illustrate this-- a 3.9L dakota gets 16-18 MPGs. a 5.9L dakota gets 15-17 MPGs. why do 2 engines, WAY different in size, get similar MPGs? what's the same? vehicle weight and aero. the hp needed to move 4,000 lbs through the air is the same regardless of the engine size, and to generate that Hp, you have to burn X lbs of fuel/hr. doesn't matter if you're burning it in 6 cylinders or 8...it's the same total amount.



Hay Tom .... then lighter weight sure helps in the ET dept ... but not-much-at-all for fuel econ. ... and the AERO of a 62

PLUS the motor is a bit down on power.
