Exhaust System Insulation Story & Photos By Jim Clark (The Hot Rod MD) If you are building a highly polished showpiece, controlling heat radiation from the drivetrain and exhaust is not something that you will have to address.  However, if you plan to drive it, shielding sensitive components like the brake system and wiring from… Continue reading Exhaust System Insulation

By Bob Wilson Last month I took my 40 Willy’s to a local car show here in the Phoenix area. It was one of those hot days over 100 degrees. I drove it home after the show and parked in the garage. After a couple of hours I went out to the garage and opened… Continue reading Carburetor Percolation

My full custom all steel Willy’s (check my build article) has a RCI fuel cell that originally was polished down. About a year after installation I noticed the smell of fuel coming from the car. Sure enough the fuel cell was weeping along one of the polished down welds. I had thought about re-welding the… Continue reading RCI Fuel Cell Company

Chevrolet first used the attached reservoir pump in 1961 and they are still in use today in a few applications. There are a large number of pumps available that will work with all of our power steering pump brackets. Any pump from a small block, big block— long or short water pump—, and some six… Continue reading Power Steering Pumps: Article provided by Alan Grove Components

General Motors in the early 1980’s started using the GM/Saginaw TC metric power steering pump. It is more commonly referred to in the street rodding industry as the Type II power steering pump. There are two basic pumps that will work well with our pump brackets. These pumps will have all mounting holes threaded which… Continue reading Remote Reservoir Type II Power Steering Pump: Article contributed by Alan Grove Components

RESOURCES     In a cold engine the fuel condenses out of the fuel / air mixture onto the passageways of the intake manifold and walls of the combustion chamber.  Fuel will not burn unless it is mixed with oxygen.  To make up for that loss through condensation more fuel needs to be introduced into… Continue reading Edelbrock Electric Choke Conversion for the AFB Four-Barrel: by Jim Clark, Hot Rod M.D.

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)
