have a 69 camaro with a 383 stroker motor.just bought the car.at 50 mph on the highway it seems to be at a real high rev thats 50mph at 3 grand on the tach.the guy thinks theres 355 in the rear but when i opened the trunk theres a new set of richmond 411s in the box.its a 12 bolt was wondring if the car would be more highway drivable if i had the gears changed.its also an auto b&m shifter thanxs jim
what size tire you running? Are you sure the trans is shifting into its final 1:1 gear? If you are running around a 26.5'' tire with 3.55 gears you should be doing around 2250rpm give or take a few depending on how tight/loose your torque converter is. To be doing 3000rpm at 50mph would mean you are running around a 4.56-4.88 gear, not too wonderful for a street car.
ill check the tire size and get back to ya.I think the car was set up for the strip it has the nitrous set up rev limiter etc on it.I drove it to N.J. from PA on interstate 95 and believe me everyone was checking out the car.Its a super clean car and want to make it more streetable jim
If your tach isn't out of whack and you are really pulling 3000rpm at 50mph you are running some seriously low (numerically high) gears in the range of 4.56 - 4.88. If you are planning on doing cruisin' on the street with the car I would suggest something more along the lines of a 3.55 gear. Even those 4.11s will be revving pretty high at highway speeds. I run 3.73 gears and hit 3000rpm right around 65mph. That is about as much gear as I would run and still want to drive on the highway.
Ill bet that it already has 4.10 gears in the rear,and either those are the old gears in the box or maybe the previous owner suspected a problem with the gear set and bought a replacement set just in case.3000rpm at 50MPH is pretty darn close to 4.10s.
