Glenn has done tons of research on this and we are both about to the point of have custom machining done.

Autometer guages have a sending unit that is 1/8" NPT.
An LS1 motor has ports machined in, but are 12x1.5 metric.

Sure there are adaptors, but the wall is so thin the adaptors twist off with MINIMAL torque. And by that, not enough to crush a seal enough to prevent a leak.

Why don't they make a 12x1.5 sender?????

The stock sender ohms out WAY different ... almost 1K ohms lower than the AM.

That's strange. I was in contact w/Cory and he sent me one. Its a nice short temp probe w/a large 12x1.5 metric to 1/8th NPT adapter. It is sturdy as the probe doesn't extend into the adapter. That was, after all, the shortcoming w/the adapters for the long probes. It is only available directly thru AM. If anyone needs one call 'em direct and speak w/Cory. That's how I obtained mine.

IAE, I need a place to put the temp adapter other than into the LG Adapter.
