Welcome to the “Bolt”! Assuming you have the stock rear that came with the truck, stock 3100’s came with a 4.11 rear and is good for at least 50-55 MPH. At that speed they are a bit noisy, but these old Stovebolts can take it! Even at that speed, they are only doing 2400-2700 RPM.
With that said, I have a 4.11 in my ‘52 with a ‘59 235 and I feel your pain. I also plan on either changing the gearing in the rear to 3.55 or installing a T5 tranny with the appropriate rear.
This is a great forum to get you where you want to go with your truck! See you around the garage forum!
