Which way should my Pistons/rod point?

And to make things worse, in the seventies there was a big fad to reverse OEM pistons in the bores to supposedly produce more top end power. No idea if this was a "good idea."

It was a great idea. The only engines that I know of (which means less than nothing LOL), that reversing the pistons and swapping cylinder banks to gain different wrist pin offsets was the 10.5-1 273 Commando engines and the D Dart 273. I've built myself a couple of them. Depending on how you build it, you can get another 1,000 RPM. You also get piston slap. The L2222NF TRW powerforged pistons (273 10.5-1) are ZERO pin off-set, probably not even made anymore. I know nothing about other MOPAR engine pin off-sets.

Old school way to know how rods are installed:...Numbers/locks to the outside, pee-hole to the cam. Real easy to remember.
