Hotchkis or QA1 all inclusive kits - which one?

If you think it is good now, add some larger diameter wheels with some 200 tread wear tires. That car will do things it was never intended to do!
Wheels and tires are on the list. Next project is a 360 block I picked up off Facebook marketplace, going to rebuild and boost that, coupled to a Tremec 5-speed but need to find some money first !
