The Blacktop piston is rather distinct, to accommodate for that larger chamber the dome is noticeably better with diminished flycuts. The exhaust flycuts remain existing but far more shallow and only the center ingestion flycuts continues to be but even that is just a very small flat circular dish machined out.
The engine’s roar, the tire’s squeal, the burnt rubber’s odor, and The strain of the seemingly out-of-Management auto hooked the spectators similar to a moth into the flame.
