...Yeah, the confusion has lead to a debate about whether a strung out Nascar/Yates BOSS small block winding 8,500 rpms in a JBL vs. the all aluminum Shelby FE big block in a Superformance is faster around the track. Those tall guys with heads sticking over the windshield need lots of extra power to compensate for wind resistance against the helmet visor just to get around the track. Weeeeeeeeeee!
