    havent responded to this in a while but maybe both of my trucks were just crap

    once the speedo would top out the rpm would not climb either and this is both trucks having aftermarket tach's i dunno maybe my trucks suck

    my stock 92 4.3 topped out around 115mph next to a friends older Iroc Camaro. i kept up with that little 305 until 120+, and i have a 5spd so it just wraps out the gears at about 41-4200 RPM

    The hotrod runs out of gear in third at about 110 (3.73 rear w/ 255/50/17s), and keeps trying to downshift if I try to accelerate much father in overdrive. I could spin the motor higher in third, but it's really screaming at that point. :D At least it rides dead smooth at that speed.

    looks like you need to check up on stuff again, because newer fuel injected motrs also have govenors

    I think he's trying to point out that it's a speed limiter, and not a govenor.
