Funny...by definition any engine built with forged internals is considered a race engine. Not to mention all parts purchased and or advertised are strictly labeled "for race only" there is no such thing as a street build or engine when we build these assemblies to the level we do. Sorry Harry...but when you go as far as the majority do the engines are then considered "race"
Its def not uncommon to compare when so many compare what racing bodies (entities) build that we all try to aspire to build. So in reality we are all trying to build or have built a race engine.
