High-compression engines in muscle cars or those transplanted into early hot rods need to use a fuel of a higher-octane rating to avoid pre-detonation (pinging, knocking).  Just selecting the highest-octane fuel available is not the best solution to the pre-detonation problem. However, choosing the fuel with the correct octane rating requires some knowledge of how… Continue reading Choosing Gasoline for Early Engines: by Jim Clark (The Hot Rod MD)

As a shade tree mechanic I assumed that when tightening nuts or bolts that “tight is right, too-tight is even better, even tighter is broken.”  This works for fasteners in non-critical areas like sheet metal attachment but not for more critical fasteners like head bolts or nuts on studs.  For these you need a more… Continue reading Selecting and Torquing Nuts and Bolts: Story and photos by Jim Clark (The Hot Rod MD)

Early engines were adequately supplied with a fuel/air mixture by simple one-barrel carburetors.  As displacement increased and cylinders were added the addition of a second barrel to the carburetor met the increased demand.  At idle and lower RPM operation a one two-barrel carburetor supplied sufficient fuel/air input for everyday driving operations.  However, extra fuel/air was… Continue reading Tri-Power Carburetor Conversion and Linkage Installation: by Jim Clark (The Hot Rod MD)

What:  There are two types of fuel injection.  Throttle-body (similar to carburetion) and port injection.   How:  Throttle-body injection places the injectors in the airstream introducing the fuel into the air as it passes through the venturi similar to the way that a carburetor does.  Port injection introduces the fuel into the airstream through ports in… Continue reading Electronic Fuel injection: Throttle-Body Injection/ Port-injection

Rotor Phasing is defined as the alignment between the rotor tip and the distributor cap terminal when the spark occurs.  This position can be very important to your engines performance.  If the alignment is incorrect, the spark will jump to the next closest terminal or another ground resulting in a misfire and loss of power.     … Continue reading Rotor Phasing: Article from: MSD Ignition
