2. Competition Cams - Wikipedia

   en.wikipedia.org/wiki/Competition_Cams

   Although founded in 1976, [2] Competition Cams wasn't incorporated until 1977, when it began by selling valve train products through satellite distribution stores. The company has acquired manufacturers of transmissions, electronic fuel injection, and nitrous oxide systems through its holding group, COMP Performance Group, consisting of 13 companies.

3. Hydraulic tappet - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_tappet

   A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower. This space prevents the parts from ...

4. Ford small block engine - Wikipedia

   en.wikipedia.org/wiki/Ford_small_block_engine

   The most common form of this engine used a two-barrel carburetor, initially with 9.5:1 compression. It had hydraulic lifters and valves of 1.773 in (45.0 mm) (intake) and 1.442 in (36.6 mm) (exhaust), and was rated (SAE gross) at 220 hp (164 kW) at 4,600 rpm and 300 lb⋅ft (407 N⋅m) at 2,600 rpm. Optional was a four-barrel version rated at ...

5. Northstar engine series - Wikipedia

   The cams act directly on hydraulic lifters on the ends of the valves and are fed with a lubrication passage drilled through the cylinder head lengthwise. The intake valves are inclined at 25°, while the exhaust valves are canted to 7° with center-mounted platinum-tipped spark plugs. The cam covers are magnesium for light weight and sound damping.

6. Desmodromic valve - Wikipedia

   en.wikipedia.org/wiki/Desmodromic_valve

   However, a desmodromic system must deal with the inertia of the two rocker arms per valve, so this advantage depends greatly on the skill of the designer. Another disadvantage is the contact point between the cams and rocker arms. It is relatively easy to use roller tappets in conventional valvetrains, although it does add considerable moving mass.

7. Camshaft - Wikipedia

   en.wikipedia.org/wiki/Camshaft

   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.
