My curiosity is getting to me. Back in the old days, when cars were cars and gas was gas, I had several 318 powered vehicles that would regularly pull 20-25 mpg on the highway. Gas isn't what it used to be. What kind of gas mileage are you expecting to get out of this super duper 318, and what is its expected cost to get that mpg? The port injected 96 318 in my 4x4 truck is only getting 10 mpg around town. and around 13 on the highway.
