I'd say that you can run stock pistons and rods, but not bone stock.
Factory assembly clearances are not supposed to be exposed to excessive temperatures, that you meet in turbo/supercharger applications.
I mean, the piston ring gaps are too small for that much heat. And even if your pistons can withstand the heat, it's the rings which would expand, eliminate the gap and then - bang! - you get either broken ring lands or scratched cylinder bores.
You can run that Paxton with stock engine with a bit rich carb tune up (too cool pistons), until you won't pull it hard.
Proper clearances differ a stock engine from a race engine in a bone stock class.
