Horsepower with mileage options

If you really want better mileage, EFI is the way to get it.

3.55's out back won't help your mileage either unless you go with some kind of overdrive.
I definitely like the idea of EFI, I was telling him that would be the way to go. He is just an old school kind of guy. He is running the stock 14" wheels, 2.76 gears. I'm all for going with aluminum heads, lol if he is paying for them. I didn't even think about an overdrive transmission. That would be a great option for it at some point.
