COMP Cams developed the process of ion nitriding for camshafts, or Pro Plasma Nitriding. [9] This is a 36-hour process that uses pulsed nitrogen plasma in a vacuum controlled environment to embed chains of nitrogen ions into the camshaft surface approximately .008” - .010” deep, significantly hardening the surface .
The GTS 300, named so because its engine's output was 300 kW (408 PS; 402 hp), was available in both Coupe and Commodore (sedan) bases. It was powered by a 5.7-litre Callaway-tuned C4B engine, based on the Chevrolet LS1 V8. Until recently, it was the most powerful Australian made production car and a true collectors item.
A camshaft operating two valves. A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion.Camshafts are used in piston engines (to operate the intake and exhaust valves), [1] [2] mechanically controlled ignition systems and early electric motor speed controllers.
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
It was the first Ford engine to feature a belt-driven overhead camshaft. Early Pinto engines suffered from excessive cam and follower wear, this was later addressed by nitriding the cam lobes and followers, and the fitment of a spray bar, which sprayed oil directly at the camshaft.
The camshaft was the HO cam with 288/301 duration. It was the top-of-the-line engine unless one opted for the "Ram Air" V-8 derived from it. As Pontiac's 1967 performance brochure said, "You can add the Ram Air induction hood scoop and new high output cam and valve springs to the Quadra-Power 400 for better top end breathing."
