So not a good idea for a street duty car then? 
I think the key to BG statement is the proper crankcase ventilation, IE vacume pump, which will probally lead to oil starvation on the wrist pins and other parts. I drive my Duster on the street with 5W20 wt. Valvoline petroleum oil with a PCV and valve cover breathers, no sign of oil starvation on any parts in three years. I shift the motor at 7300 rpm at the track  The crankshaft scraper helps keep oil in the oil pan and frees up some HP above 5000 rpm on the big stroker motors
