DUDE, I wont have my 3.73's till Tuesday,Im just going by what Ive read about the gears,so yes,an auto will do less RPM then a 5--speed!!!!!!!!!!5spd GT said:I'm turning right about 2000 with the 5spd.....
I thought an auto would have less rpm at 60 then a 5spd because of the way the trannies are geared....lol...I guess not

LOL,,LOL,,5000 launches,holy cow!!!!!!!!!!!!!!mike keirstead said:nope--5000 launches. 3 clean power shifts and 12.60s. The cars chassis is ready for the 10s

I know, I know you meant rpm's I just thought that was pretty radical(awsome!)mike keirstead said:I meant 5000 RPM launches
Thanks Don,yea,I forgot to mention Im getting a trans-go kit installed the same day,Thanks Ive been waiting for someone to tell me that!!gt90stang said:Hi,
You'll really like the 3.73s. I chose them for several reasons:
Top speed in 3rd = 120 MPH @ 6200 RPM with my 255/40ZR17s which give 829 revs/mile.
2100 RPM @ 60 MPH in OD
3100 RPM @ 60 MPH in 3rd
A friend of mine had 4.10s and was running out of RPMs at the 1/4 so he had to go with a bigger diameter tire.
Most 5.0s can't rev. over 6200 due to valve float anyways. So with 3.73s a stall converter, good shift kit and good control arms you'll out lauch those 5 speeds
Good Luck, Don
