    I have a 72 K5 Blazer with the three speed manual tranny and the 350. I was wondering if someone could tell me what max speeds I can shift at since I do not have a tac. Also could someone please tell me what my engine red lines at, so I can put on a tac.

    first-go buy a tach!
    If I told you 3000rpms or 10,000rpms how would you know when to shift without one??? If you can' put it in I will help you. I wouldn't shift your truck over 4000rpms personally, there's no reason to. I would shift for regular driving around 2200rpms. It depends on the conditions. .....PS put a 4 speed in that puppy

    it red lines I would guess around 5500, but once again why shift that high. I you want to race get a race car. Then you'll really find out how expensive a toy can be!

    I hit 102 on the highway once, that was with 35's 454 and 3.73 gears. I had the top off and the new carpet in, least till the new carpet caught some air, then I was driving with one hand and reelin' in carpet with the other.
