Norm used Holley carbs, but I think GM style cause the mopar ones were hard to get at that time, that’s why the fuel line is on the opposite side. That upside down air cleaner is a Mr. Norm piece and I’m sure the other parts were available too through his dealer. They also “super tuned” and dyno’d many cars they sold and yes....they got the sticker too. Some cars even came with superchargers, but that might be 1972s that got them
