18.2 MPG first short trip - No tuning yet !!!
First short trip in the newly road worthy but not yet finished Green Machine gave us 18.2 mpg. Went 225 miles, some city driving. Motor has about 500 miles on it now. All that we did to tune it was set the timing on the boneyard HEI, put on stock jetted edelbrock 1406. We plan on working on the advance curves and will try to tweak the carb. Planning on adding headers this next spring, tuning and headers might make it better, want to try to get 20 mpg, but maybe I shouldn't mess with it !!
(don't tell anyone it is a lowly 305)
