I have a 1980 L82 that the former owner had mildly modified in the engine and drivetrain. I am trying to guess what the rear-end ratio is. I have a 3-speed Turbo 350, and I am turning about 2,500 rpm @ 55 mph. Does anyone know what that equates to? I know a 3:55 was available after-market and special order for that rear-end, and I'm guessing that's what he used. Many thanks!

here is one  of the many gear ratio calculators available online...

if your tires are 26 inches all... it will be close to a 3.55...

did you see the articles in the tech section and in the magazine about installing a 700R4 into a late C3....
