I was wonder what the top speed and when should you shift a 5-speed with that engine. (Rpm)

I have an uncalibrated speedo with slightly bigger than stock tires (31's) and I've maxed out the speedometer, so that's something like at 96 MPH. There is a good chance that wasn't absolute top speed, that's as fast as I've gotten my truck. Generally shift 3k rpm, loses power (that's what I feel at least) any higher than 3500-3700.

Does the guage stop at 80 or 120 mph?

90. Last number on it is 80 though. Lightning a have 120 speedos

fordlover329

Thank you. I couldn't figure out which f150 had a 120 mph gauge.

Shift by feel, and top speed is 110 on a factory computer. Even though the speedometer doesn't get there.

Like the sound of that thing.
