I have figured my car put 1 million more engine revolutions on it during Drag Week than it would have if I had a .75 OD in it
I also figured out my fuel consumption per engine revolution.
I figured out that the OD should add 3.3 MPG to my current setup
I say that I would drive my car more than I do if it got better fuel mileage but the $300 a year in fuel savings doesn't pay for the cost of the 4l80e swap.
so for me, this trans swap is dead. plan on putting my 426 gen 3 hemi in the car. slap a little carb on it and see what kind of fuel mileage I can get out of it and hopefully make it daily driver capable
Your only figuring in the mileage aspect... is a million more revs worth something(meaning more frequent tear downs)... I have about $350 into my 518... not counting the drive shaft which I had to get either way
