Well if you only get 5 mpg you will need 40 gallons of gas to drive 200 miles. Pump premium at 3.50 a gallon is $70 a year, 110 leaded is about $10 gallon so it will cost $200 or $130 a year extra, if $130 a year is gonna break your buget than you probably should not be driving a gen II hemi. Also the leaded race gas tends to last longer in storage than pump gas.
