  • Chevy Big-Block Performance Camshaft and Valvetrain Events

    For a Chevy big-block the lobe lift of the intake is a very important factor. Because the cam is physically bigger (1.950-inch journal diameter) than a small-block (1.872-inch journal diameter) the lobe can for a given duration have a higher lift. However be aware that many cam companies use the same profiles for a small-block.

    Jun 22 2007 · Modern camshafts are "assembled" from powdered metal cam profiles fixtured on a steel tube and then a ball is drawn thru the ID of the tube expanding the metal and locking all the profiles in their respective orientations. The best materials can be then used for the oil pump gear the bearing journals and the cam profiles.

    The two main things are lobe lift and journal diameter. For example a .420-inch lobe lift roller cam should finish around 1.028-inch base circle size. When you request a .900-inch cam you are taking .128 inch of base circle diameter away dropping the lifter down an additional .060 inch in the lifter bore.

  • » Centerless grinding of cam and crankshafts

    Centreless grinding of crankshaft bearing journals is in many respects similar to camshaft grinding. The main differences are Camshafts are rough ground directly from the cast condition while crankshafts may have to be pre-turned. The diameter tolerances for crankshafts are often even tighter than those for camshafts.
