Using a 17mm (intake) or 14mm (exhaust) socket and an adjustable wrench, reinstall the cam gears onto the Kelford camshafts. Tighten the intake cam gear bolt to 83 ft-lbs and the exhaust cam gear ...

Weiand 8004 intake, COMP Cams 1.5:1 full-roller aluminum rockers, Carb Shop Q-jet, COMP Cams XE256H cam (256/268 adv duration, 212/218 duration @ .050, .447/.454 valve lift, 110 lobe separation ...

This cam has duration at .050 inch of 257 degrees on both intake and exhaust lobes, .594-inch lift, and a lobe separation of 110 degrees. This cam called for an installed centerline of 108 degrees.

Camshafts and crankshafts perform separate functions, but must work together in a well-choreographed sequence for your engine to operate smoothly.

VTEC vs Valvetronic. Honda versus BMW. Who makes a technology that makes for a better engine? Both technologies are used to alter how much the intake valve opens, thus how much air an engine gets, and ...

The Erson cam added a solid 23 degrees of duration on the intake side and 26 degrees on the exhaust side, both measured at 0.050-inch tappet lift. The Erson also added a whopping 0.082 and 0.062 ...

Moreover, a camshaft determines the duration and nature of the ignition process. For instance, the intake valve may open for a longer or shorter period of time during the upstroke. A small change in ...

Variable valve timing-intelligent on the exhaust camshaft changes valve timing as much as 51 degrees. During cold startups, the intake valve defaults to an intermediate position, while the exhaust ...

The cam shenanigans (shenanicams?) don't stop there. Our intrepid swappers ditch the 2AR's wimpy exhaust cam entirely for — surprise! — another intake cam. Yeah, weird, right?

It's a mechanical cam-phasing system that adjusts the intake camshaft timing depending on engine revolutions. As engine revs increase, centrifugal force alters the valve timing by a few degrees ...
