  6. Meet Dan Parker, America's Fastest Blind Racer

    Meet Dan Parker, America's Fastest Blind Racer

    Dan Parker is living proof you can't keep a good man down. After loosing his sight in a racing accident, dan got back on the horse–Corvette in this instance– and achieved the impossible, becoming the fastest blind man in America.

    “A dream changed my life forever,” Dan Parker recalls. “I went to bed thinking about my late brother – he had told me about a group of guys from France who had flown to the United States with a disassembled 50cc motorcycle in their luggage. They rented a car and drove to Bonneville, put the bike together, and each one set a different record with it. And when I fell asleep, I dreamt that I could race again – that I could become the first blind man to race at the Bonneville Salt Flats.”

  7. How to Install Connecting Rod Fasteners the Right Way!

    How to Install Connecting Rod Fasteners the Right Way!

    Properly installing connecting rods is key to long engine life. Here, we take a look at the different ways to accomplish this task and which works best. 

    There is perhaps no more important component contained in the internal combustion engine than the connecting rod fastener. Regardless of whether a particular connecting rod uses a bolt/nut arrangement, or a capscrew configuration, the connecting rod fastener's performance is critical. Understanding the details for proper installation is important for veteran engine builders and first-timers alike.

  8. Bearing Clearance and Oil Viscosity Explained

    Bearing Clearance and Oil Viscosity Explained
    The relationship between bearing clearance and oil viscosity is a delicate balance. Read on for more information on how to get it right!There are some fairly famous duos in the entertainment industry – Abbott and Costello, Rogers and Hammerstein, and Batman and Robin among the more illustrious. So it may not be much of a stretch of the imagination for an engine guy to include the pairing of bearing clearances with oil viscosity as a duo you should become acquainted.

    The typical rule that most engine builders follow is that bearing clearance establishes the viscosity of the oil to use within a given oil temperature range. Generally, the tighter the bearing clearance, the lower the viscosity the engine can use while wider clearances require thicker oil. But there are plenty of variables that come into play that are worth investigating.

  9. What is Straight-Shot Oiling

    What is Straight-Shot Oiling

    Lubrication is the lifeblood of any high-performance engine. That’s particularly true for the rotating assembly that absorbs the many thousands of pounds of combustion pressure and converts it from reciprocating motion to rotary motion to drive the vehicle. Straight shot oiling plays a major role in that brutal environment. Here’s why.

    Main bearings and connecting rod bearings must have a constant supply of fresh clean engine oil to do their job correctly. Anything less means instant catastrophic engine failure. Engine builders devote considerable effort to ensuring a steady supply of cool unaerated engine oil to the rods and mains in high-performance or racing engines.

  10. How to Clearance Your Block for a Stroker Crankshaft

    How to Clearance Your Block for a Stroker Crankshaft

    Is a stroker crank part of your next build? That factory block may need some massaging to make it fit. Here's how to make more real estate in your crankcase. 

    Stoker engine have been popular for many years, but there are some pitfalls that can bite you if you are attempting to stroke a stock-block engine. The longer throws on a stroker crank naturally swing the big end of the rod out farther toward the pan rails on any block. This can be problematic on stock factory blocks because they often do not have enough room to accommodate the extra stroke length without interference at the pan rail or other areas in the lower block or crankcase assembly such as the bottom of a cylinder. The most common area of interference is between the rod bolt nut or cap screw and the lower portion of the cylinder adjacent to the oil pan rail or the pan rail itself. To check this, you must do a mock assembly and determine where to grind the block for clearance.
