Take some serious advice here. If you wife will buy you something like that for your car, PUT IT ON THE CAR, I DON'T GIVE A #@#$$%&* IF IT'S EXACTLY WHAT YOU WOULD BUY FOR THE CAR OR NOT. Buy a spare hood, cut a hole in it for the carbs, get it painted, and act like it's the greatest thing since sliced bread. Remember that you've probably made a lot of compromises on the car about other things. My wife is very tolerant of my crack-like car and gun habits, but not to that extent. I constantly hear friends talk about their wife's complaints "too much money on the car", "too much time on the car", "you love the car more than you do me", etc. You are a lucky man. Buy her some roses, take her out to a nice dinner, and PUT THE CARBS ON THE CAR.
Besides, I think they would look great. No scoop, show 'em off.
