4.10s or 4.56s

6.17's ?? just kidding. If you do limited street driving and plan to run 1/8 mile track then 4.56 would be my pick. Back in high school my street car was a 340 Duster 4 speed with 5.13's. Never drove it more than 10 miles from home and speed limits back then were 55 max. Oh yea, the 617's were in a buddy's 69 Camaro..........
