Combo advise needed!!

1968 FB B'cuda, 030 340, 11:01 comp. heavily worked T/A heads 202/160, Hughes solid cam, 245/250- 560/575, Edy street tunnelram with 600 vac. sec. holleys, 4 speed. I plan on using a Centerforce dual friction clutch, S/S springs and a 27" 0r 28" tall tire. My question is gear ratio. right now it has 4:56 gears and can't be driven anywhere. Do you think I could get away with 3:91s? or would 4:10s be a better choice? Will the 3:91s be to high for getting off the line and or taxing the clutch? It will hopefully be at the track a couple times a month and street driven also. Our new track (hopefully) is about 35 miles away. Always appreciate the info from you folks. Kevin
