Either way you do it, there will be times you wish you had done it the opposite way...it's human nature.

I concur that unless it's a daily driver or long-range cruiser, screw the gas mileage and go for what you really want (which is really the 351/427 stroker). Sounds cooler and a bigger wow factor for sure.

Or if you're worried about range, drop in a newer 20 gallon tank with the 351 stroker motor and you might be close to where you'd be with the 289 build and the 16 gallon tank. That is until the wheels on the gas pump stop spinning and it's time to open your wallet.
