Smallblock guy, sure you can try, but if you've never camped and never bike toured, you'll be amazed by how the crap required will add up in volume and weight, and then you'll be amazed how the gearing on this bike is inappropriate, especially for an old dude.
heck I'm an old dude,also riding for over 50 years, but really, by using this bike, very likely you'll be making life really hard on yourself and them old knees, not to mention the already said factors of hitting your heels on panniers.
if you do try loading stuff on this bike, also be aware that both as a racing bike AND a 70s or 80s frame, there is a really good chance with a load on it, it will get squirrelly, loosey goosey, wobbly as Dean Martin's drunk legs.
oh, and remember the song Popcorn, I'm sure you do, that'll be your spokes. (good chance anyway)
