What gives a classic Pontiac its aura? It's a complex combination of style, racing heritage and engineering art that symbolizes performance, looks and class. An integral part of the Pontiac image is its unique and legendary V8 engine. This powerful and rugged cast iron engine is distinct from those produced by all other General Motors divisions and is single-handedly credited with launching the muscle car era. This is why we feel that only a true Pontiac heart should beat beneath the hood of a classic Pontiac. Replacing major components like the heads, crank and block, with non-Pontiac parts, taints the heart and the soul of the muscle car – it's no longer a true Pontiac, it's lost its spirit and history.

Whether it is a Ram Air 4 head or a low compression D-port head, a 4 bolt main HO block or a regular 455 block that has been blueprinted, they all say I am a real Pontiac.  At Nitemare Performance we don't make this compromise: we use genuine Traditional Pontiac heads, blocks and cranks and produce true Pontiac engines with power outputs from 400 hp to over 750 hp, that deserve to serve in the engine bay of Pontiac classics.
