Hinds,
Are you running a 4 speed or 5 speed? I run 3:27 gears with a 5 speed and a .6 split, but if I had it to do over again I would go with the .8 split. In 5th at 70 I tach 1900 RPM and in any other gear I like the 3:27s over the 3:91s in my other Cobra. These are light cars with not a lot of weight on the rear end and 1st gear with the 3:27s is almost useless with my tires. I do nearly all of my street driving in 3rd and 4th, and around town 2nd is great. And with a big block, you will have more torque and power than I have. So the lower gears will be harder to get traction with and if I were you and wasn't going to drag race, I would definately stay above the 3:73s.
