idk if i worded that correctly, so i will explain myself a little more.

i just got an '03 cobra last monday, and it still scares me a little bit (coming from an '06 cobalt ss s/c - 13.6@105 and of course it was fwd)
so without going on the highway and doing 150+mph myself, i'd like to know where each gear ends as far as mph. any input is appreciated, and rep will be given (if this site has a rep system)
i bought it from a 50+ year old man, and i doubt he had installed aftermarket gears, but you never know, and thats what i'm trying to figure out.
thank you for your time

that answers everything. T56 tranny, 3.55 gears.

 

I think 140mph is top of 4th gear.

 

139mph@6500rpm in 4th

 

thanks bigmoose
