I KNOW what Leopolds engine made. Was just involved in the sale of another AS car that was that came with 3 engines. The best of which was about 30HP behind Leopolds P5 deal. Yes I said P5, as that is what Leopold runs. His old W8 stuff was good too and now resides out west here as well. That is NOT a cheap motor at all and IMO not sure why or how a P5 is allowed in SS, just saying....
