Help me find out if my speedo is accurate

Could you guys post some speeds vs rpms's so I can see if my speedo is accurate? I got a 86 Camaro, 2.8, auto, 3.42 gears, tires are 255/50/16.

There's a place on this site where you plug in your tranny gear, rear end gear, tire radius, and rpm that gives you an exact anwer. I broke my speedo and used it to make a little chart. I would give you mine, but I have different tire sizes and I dont know you gear sizes.
