Im switching from a 2.8 to a vortec 383, my speedo only reads to 85, but is in a 87 firebird, so i have electric gauges. I know when i go down the 1/4mi track its going to go way over 85, (hoping for 105+) But anyways, it should just keep going till it runs into something then just not beable to be driven farther, and hopefully not get stuck or messed up right?
