nv 4500

[feller]

Has anyone swapped an nv 4500 into a 72 4x4? I assume it would work fine, just curious about how close the shifter would be to the 4 speed hole, I know 4 speed is off to the driver's side and the 4500 would be more center. Mostly asking cause the overdrive would be nice, and who doesn't like shifting gears?

No problem whatsoever for mine, slight modification for perfect placement on the tunnel but otherwise it works.

There is a lot of information on doing this type of swap.

Looked into this first back in the late 90's for my 72 C/30 at the time. Advanced Adapters has a nice plate adapter to allow the Dodge version to bolt up to the Chevy stock bellhousing.

As far as I know both the SM465 and NV4500 shifters are centered side to side. I think the 4500 shifter is a bit farther back. No doubt the measurements can be found by searching the internet.
A late 4x4 NP205 uses a round pattern like a 4x4 NV4500 and an early 32 spline short NP205 input can make things almost bolt up. As I recall you have to shorten the trans output by about .25". Or you can use the long input and a spacer from AA.
On pirate there are people selling oval to round adapters. ORD and others may have some as well.

Yeah I'll work on pictures when I get home. If you need a bellhouse to fit a Chevy v8 to a Chevy nv4500 early model transmission I have one blasted and clear coated with fork, splash guard etc

I appreciate it but this is all just planning stages, I am in the process of putting a vortec 4.8 into an 86 monte, this will be my first ls swap, if I like how it goes I would not be opposed to putting a 6.0 in my 72, but was thinking about trans options, cause the power and fuel econ combo is my main goal. and I haven't found too many good solutions to trannys. but last night I was on craigslist and saw an add for a 4500, I had a cummins powered dodge that had the 4500 and had almost no problems out of it until 200k, seemed strong and I liked the ratios or the feel of them and loved that 5th was more or less overdrive and 1st was low, both good 4x4 points IMO. just not sure if I would see similar performance behind more RPMs

5th in the 4500 is overdrive.
The 1st ratio was 6.x from 93-95 or so and 5.6 in 96 and up. Still low but not quire as low.

All I know is behind a Cummins with 3.73s unless it was really loaded, or you were power breaking it was useless, haha, thanks though
