Depends on the engine it rolled off the line with too. Mine is a C20 with a 292. I think it originally had 4.11 or 4.56 gears. The engine would scream at 50 MPH with the stock gears. Now I have a 12 bolt from a '78 pick up with gears in the low 3's (don't remember the exact ratio), and can do 70 when I need to. I just don't have enough power to get out of my own way now.
