So Im finishing up my first motor rebuild. And Ive ran into yet another snag. The temp sensor that goes into the stock head is too big to fit into the new Dart heads. So my question is what brand or what do I look for when buying a new one?
I believe Chevy had different size senders. Take yours to a parts store and see what they come up with. I vaguely remember running into this with my '67. If you've got stock heads, there's a stock sender available of the proper size.
Oops, I misread your thread. I still believe there are more than one size that fits Chevy heads. If you can't find one, call the vendor/manufacturer.

If you don't have a hole in the intake that will take it, then take the old sender to a machine shop...( do not get a new one if it works).
There is enough meat on the sender that you can turn it down and then tap it to 3/8 npt. Assuming your hole is 3/8.
If you can't find someone locally, the let me know... I can do it.
thanks! But Im not putting heat back in the car so it fits in that hole right under the thermostat housing. Which is really nice cause you wont see it.
