    I have a 74 blazer. Recently I swapped from a th350 to a 4 speed and now I am wanting to move up to a 5 speed, as this is a daily driver. Anyone know what transmissions might work best?? Thanks! /forums/images/graemlins/k5.gif

    Manual I assume
    NV4500 is the best option
    you keep the low crawl gear and get an overdrive
    strong as a SM465, but a bit $$$

    You could look for a Gear Vendors over/under drive unit, or something similar. That would give you option of 8 possible gear choices. /forums/images/graemlins/blush.gif /forums/images/graemlins/eek.gif

    A new GV unit costs about $1600 !
    that and you can use it in 4 wheel drive, mounts behind a np 205 t-case, so 2wd only

    Forget a Gear Vendors with a Blazer, get an NV4500.

    Think about regearing. NV4500 has the same (crappy) ratio spread as the 465, only with OD instead.

    Obviously you will lose some ratio with less gearing, but with the 6.55 1st, you can afford to.

    Personally, if the NV4500 had a deeper OD, it might be worth it, but other than OD, (which isn't that great anyways) it has NOTHING to offer over the 465 IMO, at least for the cost.

    If the gear spacing was closer, with 1st still being low, it would be fine, but it's not.
