411 compared to 373 Gears

[84inArk]

440 H.P. 383 Flat Top Stroker w/650 Speed Demon Carb, Polished Air Gap Manifold & Vortec Heads

Anyone know what the RPM would be w/ 411 gears and a 700R4 tranny w/ over drive @ 75 MPH be??
Opposed to a 373 Ratio @ the same speed.

Tire size is 15 in.

The difference should only be about 3 or 4 hundred rpm higher with 4.11's with stock tires.

And by your tire size did you mean the outer diameter of the tire is 15"? (You'd be about red line at 75 mph) Or did you mean the rim?

Tire size is 275/60/15

3:73 @ 75 mph = 2,270 rpm
4:11 @ 75 mph = 2,501 rpm

You can find a calculator for this on Bowtie Overdrives.

Just enter your tire size , transmission type, etc... and it will calculate it for you.
