Temp Sending Unit - Mixing Old with New...
I have been reading as much as I can about my not too uncommon problem having swapped my 77 engine for a new crate engine with Vortec heads. The area Gordon and I are working around next include accommodating a standard temperature sending unit with larger NPT threads in to the Vortec 3/8" NPT hole. I saw a post suggesting there is enough material in a standard 1/2" temp unit to turn it down to the thread size needed. I don't like the idea of putting the sensor up on the manifold and like this idea better, but wanted to ask the NPT experts if this makes sense to them and or if anyone out here has done this previously. Even Lectric Limited said they didn't have a good solution to this problem. Please weigh in if you can.
Thank you and best regards,
David

David,
You lost me here, I'm sorry it's late. . . but if you have a sending unit that came with the engine I should be able to match calibrate the dash unit to the new engine unit.
So if you want to stick with the crate engine sending unit, just send me it and the dash unit and I should be able to set you up.
Now this would depend on the output scale of the sender being in line with that of a stock sender, but I should be able to get this real close for you. The sender units are not linear nor is the dash unit, but as long as the increase increments are close I should be able to do this.
Email me and I will explain.

You can do this if and only if the supplied sending unit fits the same charted scale as the original dash unit. I'm wondering if cutting the thickness of the sending unit will change the responce time of the sending unit and plan on testing one sometime this coming week.

While the outside is just a ground, making the wall thinner just might change the response time to a temperature change. This might be a good thing not a bad one.

I can't wait to hear the results. Thank you for your help sir.

Sorry, I should have been clearer in my previous post. I sent my temp gauge along with a new sender to Clocks by Roger http://www.corvetteclocks.com/. This was about 10 years ago. Roger modified the guage to work with the new sender. I think he put a different resistor on the back of the gauge.
