How hot will a coil get on my 292 get when running. will it to hot to touch. I have an Edelbrock internal resistor

Mounted on it's side? I guess some are designed to be mounted vertically only.

I assume that it has an Edelbrock 3-Ohm primary coil by the description. It would be marked for 12-volt use with no ballast.

A coil will run warm but a person should be able to put there hand on it for a short period without getting burned. The thing that really heats up a coil is setting with the ignition key on when the breaker points happen to be closed. It's just an electromagnet with no where to go in that case and will get very hot the longer is sets in that mode.

I'm more a fan of proven to be good quality coils such as the Echlin brand but since they were sold off to Standard Motor Parts, I don't know how their quality is now. Hecho in Mexico is better than the made in the PRC.

55 (and I assume older) 6v point ignition systems do not use a ballast resistor. 56-57 12v systems do. If you converted to Pertronix, no ballast is used. Pertronix I uses a 1.5-ohm coil; Pertronix II uses 0.6-ohm; and Pertronix III uses 0.32-ohm coil.

I recently purchased a Fast PS50 coil (made in the USA) to use with a CRT electronic distributor. The coil is oil-filled. There is an ongoing debate whether to use an oil-filled/epoxy-filled coil, and whether to mount it vertically or horizontally. I intend to mount mine horizontally, in the original location on the intake manifold. I don't know that it matters, but it has been suggested that the coil be rotated so that the terminals are side by side (horizontal) not vertical (one above the other) when mounting an oil-filled coil horizontally.
