Looking for old posts on installing the np 4500.
Sorry to ask but I'm looking for post's on what must be done to install a np 4500 in the 67 to 72 chevy trucks. Did a search but search tools not working. I know they are a few good ones because there are references to them on other sites. Anyway can somebody who knows provide some links.
Thanks |

Is this a 4wd or a 2wd truck? What engine are you intending to use? I've done a fair bit of research into these transmissions.

Adding a od will have a effect that could be good or bad..
What are your rear gears and rear tire size? These calc will help determine highway rpms.. https://tiresize.com/chart/ http://www.csgnetwork.com/multirpmcalc.html |

This is a bit of info I threw together to help folks make sense of the GM nv4500 transmissions. I hope you can load it without a facebook account. If you can't read it, let me know, and I'll send it directly.
https://www.facebook.com/groups/2678...07231606140004 My favorite gear ratio calculator is linked below. This calculator has three different nv4500's listed. 92-94 has different ratios. The other two are identical to each other. http://www.grimmjeeper.com/gears.html If you're running a LS engine in a lightweight truck that's used for highway cruising, you'll want to gear it so you're running 2000-2200 rpm at 70 mph. A SBC 350 would prefer a slightly lower rpm. A straight-six is much happier even lower yet. If you're doing any towing, drag racing, or just like spirited driving, you'll want higher rpms. |
