how much gear for grandveiw

[kmw]

i was wondering how much overall gear ratio are guys in the big car car class
running at grandveiw?
i'm building a car to come compete there with and was there for the last race and had a blast,so much so that i wanted to race there.
so i was curious how much gear the front runners were using?
i'm building a 86 caprice, i'm guessing most guys are running 2nd gear in the trans?
thanks in advance

3.73 gears with the car in 2 gear you will be fine

thanks, i appreciate the help

it all depends what trans your using-- 200m,350,400,powerglide, or an over drive unit 3.73 a little steep , too many rpm's , overheating issues,and valve train problems will happen, remember alot also goes into figuring this out-- tire diameter, what ratio your trans is.. and in what gear.1-2-or 3 ?? what I recommend is to use what is in the car from factory, try different gears 1-2-3 and see what your car does. if you then feel you need more gear then change it then.. Getter ready for practice day and test her out...

Most high banked 1/3rd mile tracks/racecars like a final drive gear between 6.00 and 6.30....................:rolleyes:
Tire diameter, rpm power range and track condition must be used to formulate your exact ratio.................;)

its the gear u guys told me to run im hitting 5200 rpm and have no problem

[richardpetey]

Mr. Thriller, your final gear is approx. 570 with a THM 350 in 2nd gear, thats a great gear for a wet track......................:applause:
As the track gets tacky, you'll be getting a lot more grip and your need for a higher numerical gear will increase...................:rolleyes:
You can change this ratio with a bigger tire, different final drive ratio or higher engine rpm capabilities.................:cool:
Your car will be better in the beginning of the race, the dryer the track gets the more cars with a higher final drive gear will have the advantage...........:eek:

That is pretty cool! Thanks for sharing =]

thanks guys, i'm well aware of how to calcuate gear ratios with trans ratios and tire sizes, i was just wondering what ratios guys who were running up front were running, i was guessing i would need 5.57 or more
thanks again for all the help, look forward to getting up to grandveiw to race
instead of just watching.
