Edelbrock Releases New Performer RPM CNC Heads For Pontiac 455 Engines

The mighty Pontiac 455 has long been a favorite plant of muscle car fans, drag racers, and guys who simply love ground pounding torque in spades. The engines have a devout following and even those outside of the Pontiac tribe understand that there is huge power potential locked in that combo. Well, Edelbrock has allowed the masses even more power with the release of their CNC ported Performer RPM head. These babies feature a new spark plug location, new combustion chamber design, and a pair of options for combustion chamber CC displacement. Larger 87cc chambers are available for engines in the 9.5:1 range and smaller 72cc chambers are available for you fans of big compression out there. We’d ramble on, but Edelbrock says it all below –

Pontiac Performer RPM CNC Cylinder Heads for 455 c.i.d. Engines

 

TORRANCE, CA (April 29, 2014) – Edelbrock Performer RPM cylinder heads for 455 c.i.d. Pontiac engines are now available with a CNC machined chamber.

Performer RPM CNC cylinder heads have the same specifications as Edelbrock’s Performer RPM cylinder heads for 1962-79 455 c.i.d. Pontiac engines, but feature a revised CNC machined combustion chamber design with an all-new spark plug location for improved performance. Performer RPM CNC cylinder heads are available in two chamber sizes. The 87cc chamber version is ideal for 9.5:1 engines and will deliver excellent street performance on low octane fuel. Performer RPM CNC cylinder heads with 72cc chambers are best for higher compression engines. Both are patterned after the same port flange configuration as the 1969-1970 Ram Air IV Pontiac cylinder head.
