RE: top end speed of 3.73, 3.90's
My '99 automatic with 4.10's turns around 2850rpm's at 75mph. Double that and you get 5700rpm's and 150MPH if it had the power to push it that far. Auytomatics have about a 30% drop in OD or about 70% of the final gearing. Anyone know what the 5-speeds have for OD? Mark

Top speed with a 5-speed??? No way... Or is that the fastest you've been?

My car came with 3.27 gears and i remember racing a corvette up to 138-140mph ........now with 3.73's of course the car pulls harder and faster but just a little while ago i had it up to 135mph in 5th gear and it still felt like it had more in it, the rpm range wasnt done yet either........I have a SCT tuner that took the top speed and rev limiter off also if that helps.

Ive only taken my mustang up to a 155. SCARY AS ****ING HELL. My car was shaking like a bitch and everything was so loud. Then I took the vette up to 185 and was smooth as can be, very quite. I love that car.

i think i will go with the 3.90's, and i beleive that if i cant show dominace by 100 then i shouldnt race the car, however there are also alot of cars just as fast or faster so if i have to prolong the race i want to be able to, but thanks everyone for your help
