Need Gear Vendors OD Dimensions
I know there were a couple of the Squarebody group that had GV OD units in their trucks. I looked on their website but don't see the dimensions to get an idea if one of these units will fit under my truck w/o a domino effect. They list the tailhousing assembly circled in yellow @ 12.25" (TH400/mech speedo app) but don't list the dimensions of the other section circled in red.
This could possible interfere w/my exhaust crossover and/or exhaust flanges. Does any have the length for the adapter portion in red?

Re: Need Gear Vendors OD Dimensions
A friend has a new one and about to install it, that was from the adapter to the rear seal.

Re: Need Gear Vendors OD Dimensions
So that's those two pieces combined, and it replaces the 4" tailshaft?

Re: Need Gear Vendors OD Dimensions
Would it be possible to snag a pic of the assembled unit if you're able?

On the ones I've installed, shortening the driveshaft is a must, and sometimes changing the exhaust around if you have an X pipe. Sometimes floor mods are needed in some cars as the tunnel gets a little tight back there on some models. |

Re: Need Gear Vendors OD Dimensions
My 83 C20 has a GV unit but I have a SM465 granny so the adapter is different. Driveshaft must be shortened and rebalanced - that balancing is critical or you will get a bad vibration.

Re: Need Gear Vendors OD Dimensions
I knew the driveshaft had to be cut & re-balanced. It was the closer inspection of the length that surprised me. Might re-think the 4l80e....

Re: Need Gear Vendors OD Dimensions
And there is also the option of using a 4L80E and GV so you get double overdrive. With the double overdrive setup on my vehicle, the RPM's at 60 mph is 1250 RPM's. The engine is barely off an idle at that speed.

Re: Need Gear Vendors OD Dimensions
Visually, that has more bulk to it vs what I saw from the dimensions pic on their website. What is your buddy's specific app? Mine is a th400/mechanical speedo so I wonder if that's part of it?

Re: Need Gear Vendors OD Dimensions
The unit is not bulky. However, the length combined with the NV5600 transmission and NP205 transfer case creates quite a short drive line.

Re: Need Gear Vendors OD Dimensions
Used to be a guy in town, 55 chevy 502 bbc TH400 and GV overdrive ran mid 11's did 1-2-2 over-3 over at the track.
Seemed tough enough and fit.

Re: Need Gear Vendors OD Dimensions
Will he be shifting the trans x-member back? it's difficult to visualize if the mount is affected. I recall it being part of the case vs the tail housing but need to crawl under mine to confirm.

Re: Need Gear Vendors OD Dimensions
Definitely tough enough, they are rated to about 2,000 hp. It's what most of the drag week guys with auto's use that race down into the 7 second zone at over 200 mph and then drive the car between tracks.

Re: Need Gear Vendors OD Dimensions
If you read the GV website you will find that they say adding a GV to an overdrive transmission will not increase fuel economy, just create a better towing experience.
