This is a good discussion.

I will spend a considerable amount of time driving at highway speeds and keeping rpms down is a big plus. The .64 5th seems almost mandatory. If I was doing more slow speed driving or hard core road racing then I would go with the .85. Lower rpms = much less noise and much happier wife, and the mileage will improve some.

For rear end ratio - I would have thought 3.54 would be almost too much for the massive torque a stroker will put out. What are most of the guys with big FEs running? My guess is the 3.54 would still be OK for highway driving, if I have the .64 5th gear.

Patrick,
Have you driven or rode in a Cobra similar to yours with less gear ratio than you have?

#178 has a 400hp small block with 3.54 rear end. It is not quite enough torque multiplication for the car. 3.73 or so would probably be better.
