  • How to Build Racing Engines: Crankshaft Selection Guide How to Build Racing Engines: Crankshaft Selection Guide
    A high-end racing engine can produce a combustion pressure of about 1,400 to 1,500 psi. For example, if you apply that pres­sure to a 4.185-inch-diameter piston, as found in a Sprint Cup engine, it translates to a force exceeding 19,000 pounds against the rod journal for every cylinder. That’s a staggering compressive load even under non-dynamic conditions...

  • Camshaft Basics Camshaft Basics
    Pushrod based engines use two basic types of camshaft; either flat tappet or roller tappet. It’s a little more complicated than that, but it basically comes down to the type of lifter. Up until the mid-eighties most production engines used flat tappet lifters with a crowned face that rides directly on the camshaft lobe...
