You see times and what transmission build people used to go fast, but what you dont see is the rest of the setup. What rear gear do the 700-800 rwhp guys run? What stall speed? (And yes I understand weight and cam play into that question). What size rear tire? Ive got a 700rwhp 3600 lb car almost together i was gonba try to figure out some last min tweaks

I would think power adder type would also play into this. What are you running to make 700WHP?

edit: assuming nitrous from your avatar? lol

there are charts online to be found where you compare your car's weight and HP and it will give you a very close approximation to quarter mile trap speed. Use that with your tire size and rpm you will be turning to get a rear gear number. You might have to go up or down a little after you get it to the track, but it will definitely put you in the ballpark.

Yes it will be a 200-250 shot on a well built 383. Im thinking a 3.42 or 3.23 would be a good start but I wanted to see what others have used. I know traction will play a huge factor with the low gear ratios on the 4l60e

Im at about 850-900 whp turbo car at 3900lbs. I run 325 gears and a 3600 stall in my 4l60e.
