Just a 6....Bob you are a real sleeper,that is a real race engine turning 10's, it would be lucky to turn 16's if it wasn't.You definatly have your act together,must be fun blowing away bigger engines! I said the steeper gears were useless on milder big blocks ,as in his application, for 2 reasons. 1st you waste all that beautiful low end torque and 2nd you'll be shifting outta 1st at 10 mph, gets to be a pain when the cobra is a cruiser.Your race cobra is perfect with the low gears,you probably start off in 2nd around town,i used to do that with my mustang also.
