Took it on the longest highway drive since I got it on the road and it definately needs 3.73 or 4.11 gears when using o/d,I have a vacumn gauge on it and even at 70 and 75 it was hard to keep the vacumn above 10 so it needs to spin a little faster. I wish I would have been a little smarter when rebuilding the engine as I would have had a custom grind cam made so it would work better with taller gears.
