You gotta be kidding, a super charger or a turbo in an Eagle. Only if you're a part of the go fast crowd. Which Eagle's are not, usually.
I remember taking an Eagle with a V-8 in it for a test drive. Way to much power, Accel, speed for safe driving. This was in Illinois about forty miles west of Chicago. The owner had done a really great job of putting a 360 ci into it. He used AMC coils from a Concord, dual exhaust, and the 727 transmission. Extremely tight fit because the engine center line in eagle's is over to the right to make room for the front differential. The reason the car was up for sale was that the owner's son had accumulated to many speeding tickets.
