Re: 67-72 Electric speedo
I've read so much my head hurts. I have a couple questions.
1) I'm running a 4.8L with a new style 2006 nv3500, can i run this with my setup? 2) Are you still selling templates or is someone else? 3) Is anyone making a complete kit on here? Thanks

2) Yes, I still have them. 3)No one is making a complete kit, but the parts are pretty easy to find.

Re: 67-72 Electric speedo
My 4.8 is a 99 or 2000 I can't remember for sure, the nv3500 is an 06.

Re: 67-72 Electric speedo
It will work on a 99 or 2000 no problem.

Re: 67-72 Electric speedo
Hi Eric,
I have two questions for you- does the LS motor run at a higher oil pressure than the old Gen1 350? if so, would an 80# oil pressure gauge be better to use (for keeping the needle mid-scale) instead of the 60# one ? Also, what is this ? |

Re: 67-72 Electric speedo
I think oil pressure is more dependant on how good of shape the engin is in, but mine do seem to run a bit higher than the older engines. My gauge goes way over to the right on start up and stays to the right most of the time, so if you want the needle in the middle an 80# gauge would probably get you there.
The black box on that cluster is a relay I was using for another purpose, you wont need it.

How can you get the mileage to match current speedo?

Re: 67-72 Electric speedo
I am currently working on the wiring for my speedo swap and it appears in the photos that a relay is used in conjunction with the volt meter. Is that required?
As to Prodjays question about the odometer I just reset mine yesterday. It's a little tediuos but it's not that diffucult. |

I don't really know how to explain it, but you just kind of have to mess with it a bit. Once you take it out and play with it, i think you'll see how its done.

Re: 67-72 Electric speedo
Thanks to Ls1Nova71 I have started on my Squarebody swap to digital, even though I don't need it yet. Look at how close the S10-Speedo lines up with the Squarebody speedo bezel. Looks like the only thing I will have to modify is the odometer hole as it is a tad too small for the Odometer out of the S10.
The screw holes to mount the digital speedo even line up!

Re: 67-72 Electric speedo
this speedo you made does it do a full sweep? or does it stop at 100 like they do in a s10?

Re: 67-72 Electric speedo
It stops at 120, that is where the little stop thing is. At least I think it should, to be honest I have never had the truck above 100. When you say S-10's stop at 100, is that all the faster the truck will go before the speed limiter kicks in, or does the needle just stop there? I can't remember if there is a stop at 100 on the S-10. EDIT; I just looked at my S-10 speedo pic, and there is a little stop at the 100 mph mark that keeps the needle from going any further.

Re: 67-72 Electric speedo
so we then assume with the needle bump stop moved down that the speedo will then go up to 120?

Re: 67-72 Electric speedo
Yes, it should. I do know that if you remove the stop the needle will go all the way back to the bottom of the first stop, but they can sometimes get stuck, that's why there are stops.

Re: 67-72 Electric speedo
I'd be interested in buying one of these as well.
You could easily have a business on your hands with not just these, but other classic vehicles that are popular with LSX swaps. |
