MPG The Best Of Both Worlds

overdrive will help a lot. i think you could do a full t5 5 speed manual trans swap fr about 2000. so probably carb and cam and tune it then see about od. my boss has 3.23 gears in his big block car and gets good enough mileage to daily drive it. if you really wanna drive it go pick up like an 8 1/4 rear with the 2. something ratio and that will get more mileage i think lol. but there are a lotta cons to the weaker rear end
