The hobby has changed so much in recent years. Used to be only Classics were restored
or modified but anything and everything seems to be included anymore. For racing the
easiest way to hp was usually chosen.But some guys like to be different or do something
that is more difficult or interesting.
It's pointless to argue which is best...my engine builder says anything can be made fast
nowadays...isn't there a 4 cylinder Maserati that is around 700 HP?
Back to the original question..why do mopar guys need a 408?
