Rich, take the few extra days to oil the hinges and rollers on the garage doors, sweep all of the dust out of the garage, seal the concrete again, clean the windows, get rid of the cobwebs, and convince all of the reptile "squatters" in there that should move elsewhere.
It'll all get there in good time, then you'll be sorry for all the horsepower. More HP = new tires, more gas, speeding tickets, more oil changes, and more mods...............and the list goes on.
BUT.........it will probably sound like a bear, and go like a cruise missle on steroids
