While doing the compression testing on my 2.25 (that has sat for 30+ years now) the coil (new) got hot...not just hot, but burn the crap out of you hot! Again, this was just during the compression tests, a few seconds at a time. Is this normal? If not, any ideas as to what to look for?
Thanks,
Mike

Not normal. It should not get hot, or get that hot. Is it hooked up properly? Are the points set and gapped properly?

The points are set and gapped correctly, I'll double check though.

Also - be sure not to leave the key in position 2. One click clockwise. That could contribute

Hi Mike.
Might be the type of coil bought.
is ' use with resistor ' written on the coil ?
I had a hot coil. This is the reply I got.
'' Use with a resistor '' means that it is a six volt coil that is run in two ways . When starting the coil receives a full 12 volts through six volt windings , this helps cold starts when the battery can't supply the starter and ignition with a full current . Once the starter solenoid has cut out the ignition current is switched through a resistor that reduces the nominal 12 volts down to six , without it the extra current will burn the points and overheat the coil . Resistors are usually big ceramic blocks , about half the size of a match box and screwed to the fire wall somewhere .
I change to a non resistor type, and it stayed cool.

It's a Proline Coil purchased from our hosts here. Will look for anything about a resistor next time I get to the truck. Thanks for the help!

Be sure to use a points coil with a points distributor and an electronic ign. coil with a breakerless distributor. If a Pertronix ignition is used in place of points, I think they also require a points type coil. This on top of all the rest of the helpful hints.
