Lots of good advice here, I will add my thoughts.
First off, if it is a quality restoration, I would be tempted to keep it original, or as was suggested, build a hot 6 to install and have fun with while sitting the original up on a shelf.
Building on that thought of it being a quality restoration, maybe it would be best to sell it and buy one with a good body just waiting for an engine upgrade.
Second off, it is your car, how do you want to drive it? Sounds like 6 banger performance isn't going to cut it for you. Maybe having the car perform to certain standards is more important than originality.
I went through similar anguish: my 65 Fastback is an original GT, came with A code 289 and 4 speed. Great combo for original rebuild and I was started out with that thinking. However, it needed a lot of sheet metal work, so pretty much total rebuild. I have had it many, many years so it has some sentimental value. I drove it in it's glory days, I now want to drive it with today's performance. So it is being built with modern competition level suspension, brakes, electronics, Coyote motor and 6 speed. I am forgoing all the non functional Shelby add on's, will wear original GT emblems, rocker stripes, very close to original looks but will more than hold its own with modern cars. Yeah, not for the purists but what will make me happy.
