Re: water temp sending unit?
The old sender is the wrong size for the vortec head it is too big so here are some options.

Re: water temp sending unit?
Keep in mind the new sender may not produce a correct reading with the stock gauge. You'll need to verify normal operating temp with an IR gun compared to you gauge reading. I went the vortec route with a 3/8 sender in the manifold and the stock gauge is way off. I ended up installing a set of gauges under the hood so I could monitor engine conditions.

Re: water temp sending unit?
OK, after reading all of the comments ... does anyone have a part number for a temperature sending unit that will work (without funky machining/tapping) for:
1. 67-72 C10 350 V-8 2. Intake manifold mount (such as for a GM Vortech intake, Edelbrock intake, etc.) 3. Normal temp gauge (not idiot light type) |

Re: water temp sending unit?
Intake manifold mount is no problem. Every intake I have seen had at least one 1/2" NPT port. The stock sender will screw into that. You only run into trouble when you try to put a sender into the head.
