The easiest place is to tap into the plug beneath the starter. You'll need an adapter also.

The above two posts are for electrical gauges. You don't want a mechanical. It means you have to run a coolant line directly to the gauge. The electrical ones are only about $50, and for the water temp the best place is above the starter in the block. You will need an M16x1.5 adapter.

If you have headers, and can easily access the #8 plug, then its very easy to get at the coolant plug in the head and put the sender in there. Took me about 5 minutes to do. Now if you've still got stock manifolds OTOH...

If you want to know what the water temp is leaving the motor, drill and tap a hole in the top of the water pump.

Most of the Speed World Challenge Vettes I've seen do this.

A 5/16" drill bit and a 1/8" NPT tap is all you need ...
