| cams understanding cam profile terms ramps the parts of a camshaft lobe that actually initiate the lifting and descending movement of the lifter are called ramps ramps include the lash ramp the opening ramp and the closing ramp camshaft lobe ramps are ground to have different rates of lifter movement in terms of velocity and degrees of duration as measured in degrees of crankshaft rotation the lash ramp of a camshaft lobe is a mid-point location between the opening ramp and closing ramp the opening ramp of a camshaft lobe is the point where the lifter just begins to lift until the point that ... | |

| cams lift lift refers to maximum valve lift this is how much the valve is lifted off its seat at the cam lobe s highest point valve train how is it measured valve lift is the amount usually in inches that the valve is lifted off of its seat it is usually measured with a dial indicator at the tip of the valve lobe lift is the amount usually in inches that the cam lobe increases in radius above the cam base circle tip to quickly find maximum lobe lift measure the base circle of the cam and subtract it from the thickness across the cam lobe s highest point see the diagram below tip maximum valve ... | |
| camshafts camshaft technical information cams valve train understanding camshaft specifications lobe separation lobe separation is the angle in camshaft degrees between the maximum lift points of the intake and exhaust valves.it is the result of the placement of the intake and exhaust lobes on the camshaft tight lobe separation angle 106º to 109º wide lobe separation angle 110º to 118º pistons how is it measured lobe separation can be measured using a dial indicator and a degree wheel but is usually calculated by dividing the sum of the intake centerline and the exhaust centerline by two lobe ... | |

| cams flat tappet or roller manufacturers and racers have used flat tappet camshaft systems over the years with great success however manufacturers and racers favor roller tappet cams when rules permit their use because roller cam designs have distinct advantages over flat tappet designs valve train friction sliding frictional forces are higher than rolling frictional forces therefore a roller cam takes less horsepower to turn and generally does not wear out as quickly an added benefit is that roller tappets do not require replacement when changing cams and if pop-up solid roller tappets are used ... | |

| cams 10 compare the reading on the degree wheel with the in opens specification on the cam card if it does not match your cam is either retarded or advanced for example if the degree wheel reading at 0.050 comes up 10º before top dead center btdc and your p/n 00010 cam card lists the 0.050 intake opening at 8º your cam is 2º advanced if the degree wheel reads less than 8º your cam is retarded if either is the case proceed to step 11 if it matches your cam is installed as designed valve train pistons rods 11 so what do you do if your 0.050 opening lift point doesn t match the cam card or you ... | |
