morton is the epicenter for shittalking about cars that both don't exist and have outrageous mods. Unlike Pekin, where everybody claims to have a slow car but won't pop the hood, yet want to race for money. Morton=outrageous claims of supremacy; Pekin=internet benchracers who slowtalk and hustle when it's gametime.
A twin turbo morton car translates to a dual overhead cam nonturbo in 'restoftheworld' lingo.
