    depend upon what RPM your motor runs best at. 3.08 for the lowest ratio on up. Tire size also affects this # phil

    Guess I should have stated it differently
    What I meant was how much total overall gear ratio are guys running up there
    Something close to 5.60 ,more ??less??

    Most guys wont tell you what gears they use. I will But I use a Pontiac motor. I used 2nd gear turbo 350 with a 3:08 rear = 5:83 . My car won a few races and was always competitive. If You go Chevy motor you will need more gear. phil

    Thanks Phil but the gear ratios don't add
    up the way you describe them
    3.08x 1.52 is only 4.68
    Anyway a if you are running a 5;83 thats probably close to what i d expect
    Was just trying to see if gview gear was close to big d
    Thanks again
    hope see you in few weeks

    Damn your right I must have used obama math. But I do use a 3;08 in 2nd gear. You would want more gear for Gview then BD. phil
