alright i just bought a 90 sc auto. i ran with my buddy that has a 15.3sec car. i thought the car was stock? the car runs 2000rpm doing 70 down the freeway. does that sound right for stock gears. what should i run with 3.73? what kinda of shift kits do you guys use. and do they shift hard all the time. do they act like the j-mod in the 96 birds?

i've got 3.73 gears in my 94 sc and at 70mph i'm running about 2300 rpms.when i had stock 3.27's i ran about 2000 rpms

70 MPH @ 2000 RPM's is right for 3.27 gear, I have the same in my 90 auto

that just seems high for a car that redlines at 5000rpm
so i can get away with running 3.73 in the rear on the highway. i drive from ohio to michigan about 180miles every month
