By today's standards the Green Brick is half a step over a stock rebuild. Torsion bars are too small, alignment is very conservative, brakes are a decent improvement over stock but no where near some of the big disks available now (although later versions of the Brick got Viper calipers), tires were pretty small although a decent compound. And yeah, the original version didn't have that much power either, although again that was upgraded later.
