Im trying to figure out wether to run 3:73 or 4:10 gears in my fox body.

Its just my fun car, its gonna be 90% track car and driven too and from work everyonce in a while, And to bradenton everyonce in awhile.

my main concern with 4:10s is taking it on the highway to bradenton, if my math is right i would be cruising at 3500rshared_pm at 65mph.

But I know at sunshine which is were the car will be ran more is sunshine so 4:10 would be best there.

Its a 89 foxbody 75` non roller 302, carb`d, C4 auto.
last dyno`d at 185WHP, once on nitrous it should do 275-300WHP.
With a 27x10.5 ET street cheater slick

c4 has
1st = 2.46
2nd = 1.46
3rd = 1.00

 

3:73's all day long.

 

are you sure itd be THAT bad? im sure its different with the auto and all but i have 456s with a 26 tall tire on my car and i can go faster then 65 while being below 3500rpm

id personally go with whatever your car is going to perform the best with for 1/4mile, thats what i did and i dont regret it one bit

however the next set of tires i buy with be 28 tall so when im driving around town it'll be similar gearing as to when i had 410s

 

or you could always get 390s lol

 

i was leaning more towards 4:10s because of the c4s gear ratios

which i added to the first post.

 

65 mph should be around 2,000 - 2,500 rshared_pm max

 

What size rear tire are you going to run?

 

Right now it is 225/55/16 if i remeber right, but not sure on what size it will end up with, either a 26x10 or 28x10

 

with which ? 3:73 or 4:10

 

or you could go with a 27 tall tire? lol

wats your setup like?
NA + spray? boost?
