    I had 3.73 in my old ride I thought they were great, my Camaro has 3.42 but I think I would like to go back to 3.73 someday. My car is for in town street use, not much long term highway driving.

    also gas was .89 cents a gallon! Was it the chevy engineers that thought snot green shag rugs were a good idea too. Jk

    Bump!
    Let's bring up this topic again!
    I want to hear more opinions on this. What I'm starting to wonder is:
    I'll bet the guys at GM figured that they might have a customer buy one of these cars and run it like hell clear across America! If you guys think I'm wrong about that, let me know. I can take it. But, I think back in the low gas price, drive it like you stole it days of the 60s and 70s, the engineers knew a poo load of folks were gonna buy the new car in LA and run it like a raped ape to the other coast!
    Not saying its "good" for the car but, the idea I am posing is-
    Maybe we're all too worried about gears and RPM ratios than we should be! Might not be "bad" for an engine to turn 3500 @ 65 mph if properly cooled and what not.
    I too am contemplating this gear to driving conditions thing because I'm like everyone else. I want the best of both worlds without hurting my engine.
    If you have a 350 tranny, you want good take off power AND good long trip freeway gears, what is the "real world" solution?
    Maybe I should just keep my 3.42s but, if someone here says 3.73 would be fine for a 500 mile trip at 65mph, I'd be interested (and TICKLED!) to hear their thoughts!

    In the eighties my Camaro had 4.56s and 27 inch tires, every weekend in the summer I drove 140 miles after work to go home, and back again Sunday night, and many trips from Saint John NB to North Sydney NS to catch the ferry to Newfoundland a distance of 375 miles. Usually drove around 3700 to 3800 about 65 mph. engine lasted 14 years before it needed a rebuild. I used sae 30 quaker state oil and changed the oil once a month. when I finish restoring my Camaro I plan on running 3.73s with a 28 inch tire which will be about 3000 rpm at 65 which will be fine for a trip from Saint John to Blue Mountains to Ontario which is 1100 miles. The Camaro did come with 3.73s which were a nice gear ratio with a manual trans which I plan on using, a friend is building a M-22 for me

    Depends on what transmission you have ,Have a Supercharged 1979 Z-28 RS Camaro Super T-10with 3:42 gears.a 28 inch tall tire, Goes around 60 MPH at 2700 RPM .And gets around 24 MPG depending on how you drive , I also have a 1981 El Camino SS ;dailey driver290 HP 350 Turbo 350 ,3:42 gears 27 inch tall tire, gets about the same gas mileage.

    GM Put the 3.73 in them. 4 speed has a 1:1 in 4th. I drove mine to Florida and back no problem at 70mph+ the whole way, 24hrs straight through.

    I love my 3.73 gears and wouldn't run anything else.
