COMP Cams CL20-223-3 Details

Chrysler 273-360ci Small Block 1964-2003

Note: The basic 273-360ci engines, produced since the mid-1960's, have remained relatively unchanged as far as the valve train is concerned. The 1964-91 engines used shaft type rocker arms which required some special changes in the camshaft design to allow oil to flow to the top of the engine and into the rocker arm shafts. Most of these early engines featured either grooved or offset holes in the third and fourth cam journal. In some instances a combination of both grooves and holes were employed. You must remember that if your engine has shaft type rocker arms there must be some groove or oiling hole combination on the cam journals. Chrysler began producing engines with hydraulic roller cams in 1986. These early roller cam engines still used the shaft mount rocker arms and had oil holes in the #2 and #4 bearing journal. Early 1986-91 318ci/5.2L and early 1987-91 360ci/5.9L engines equipped with hydraulic roller camshafts and lifters will allow conventional hydraulic, mechanical or roller camshafts and lifters to be installed in these engines, providing the appropriate components are used. In 1992 the new Magnum ''A'' engine was released using a pedestal style individual mount rocker arm design that oiled through the pushrod and did not have oil holes in the cam. There were also two different styles of snouts on the cams, the longer snout (.950'' from the first step) accommodates a fuel pump eccentric and the upper timing gear while the shorter snout (.650'' from the first step) came in the fuel injected engines that do not use a fuel pump eccentric. Using the wrong cam core will result in engine failure. It is very critical that the new cam match the old cam's characteristics.

Great for street machines, largest cam for stock converter, 273-318 works best with 2000 stall.

Comp Cams 'Xtreme Energy' Hydraulic Flat Tappet Camshafts

The Leading Edge of Valve Train Technology

Comp Cams Xtreme Energy series are perfect for any street or street/strip application where both throttle response and top-end horsepower is desired. These camshafts are designed to take advantage of the latest and greatest in valvetrain technology . Their aggressive lobe design produces better throttle response and top end horsepower than other cams with the same duration @ .050'' lift, while delivering increased engine vacuum. We do not recommend the use of stock valve springs with these camshafts due to the aggressive lobe designs.

Features:
  • Quicker opening lobe profiles deliver increased responsiveness & more area under the lift curve
  • More vacuum allows an increase in duration for improved performance and assists power brakes
  • Excellent performance in street carbureted applications
  • Best performance with aftermarket intake manifolds, headers, lower gear ratios
