That is about all it is good for. The 4.11 makes it worthless for freeway cruising. Have a friend who inherited a 68 Cougar GT-E with the 427. PO put on triple carb and a 4.11 rear. I've been in the car and at 65 the rpm is way up and the noise. I couldn't drive that car 100 miles for a cruise.Looks like a fun car. Burn out machine
