'70 Dart 392 Project; what direction?

Thank you for the input! I have some time to figure out what direction to go on rear suspension but you make a good point about cruising vs racing. My buddies 70 duster has hotckiss rear springs and front suspension upgrades and it handles extremely well! Traction control and a fat tire is something to think about.
I’m fairly set on megasquirt and a new throttle body. After tuning through tuner studio on a friends car and helping him wire it up I’m not too worried about it. Pretty straight forward. Especially since I’m not running nitrous or forced induction.
I should have my shortblock assembled this weekend. Need to pickup a few things at the dealer (rod bolts and the freeze plug that covers the rear cam bearing). Hopefully have my heads back this week as well. I still need my holly mid mount setup, oil pan (waiting on k member first to see if there’s any chance of factory pan working with the power rack n pinion), and brewers performance flywheel and clutch setup for my 833.
Don’t judge me too hard but I bought Chevy orange engine paint…. ‍♂️ Seemed like the closest match to the body color lol
