  • Flathead Ford Heat Treated Valve Guides
    Flathead Ford Heat Treated Valve Guides
    x
                

    The Flathead was designed to run on fuel with high levels of lead, but even with leaded fuel, the stock valves will eventually hammer the seats out, which will close up the valve lash and leave your valves hanging open...that is if you don't seize a valve to the guides first!

    Remember what year your engine was built and how fatigued the valve train components are. Henry may have built them right with the technology he had available then, but this is now and we have the modern components you need.

    These Flathead Ford valve guides are heat treated to be compatible with today's low-lead fuels. Fits 1932-53 engines. If using in a 1932-48 engine, you will have to use 1949-53 style retainers, keepers and valves.

  • KRC KRC40400360 Adjustable Idler/Tensioner Assembly, Small Block Chevy
    KRC KRC40400360 Adjustable Idler/Tensioner Assembly, Small Block Chevy
    x
                

    KRC's adjustable idler - tensioner is used to keep proper belt tension and prevent belt slippage when using a mechanical fan. This can occur on both single drive belt and pulley systems that have a steering pump mounted of the front of an engine.

    KRC's idler tensioner is essential on dirt cars. Belt slippage can occur on cars that exceed 7,000 RPM and/or use a large or heavy fixed fan blade or a fan blade with a lot of pitch, which potentially causes overheating & pulleys to wear faster. This occurs on both single drive belt and pulley systems with a power steering pump mounted on the front of the engine. 

    Fan belts and pulleys work to slow down the fan. The belt slips because it is stretching to slow the fan. The belt heats up as the the the stretching increases. The only way to properly tension the belt is with an adjustable idler/tensioner. This keeps the engine running cooler because the belt is tighter. This will allow faster acceleration out of turns and harder braking on corners.

    • Designed for GM 602 & 604 Crate Engines
    • Use with KRC serpentine drive systems
    • Assembly contains:
      • Idler - Tensioner

    Speedway Motors is your Flathead Ford specialist! We've got you covered down to the smallest components, like this replacement oil pump drive gear. This gear fits on the rear of the camshaft and drives the oil pump. It's designed to fit 1949-1953 engines with D-shaped cam snouts, but can also be used on 1932-1948 style engines by modifying the cam's rear snout.

    AFCO 21207X Three Stage Torque Link
    x
                

    The "three stage" torque link provides adjustable progressive action for ultimate torque control and traction. Torque is absorbed by the coil spring to provide the initial forward bite. As engine torque increases, the poly bushings engage to increase torque to the rear tires. Engagement point of the poly bushings can be adjusted independently from the coil spring to allow for changing track conditions. 

    Due to its unique twin shaft design the engine side and brake side operate independently. This allows corner entry and exit to be tuned separately. Bushing/spring pre-load is always maintained. Also the brake bushing works more effectively because it's not loaded with engine spring pre-load. The car turns better during decelleration as a result.

    This complete stand alone plain electronic fuel injection system supports up to 500 horsepower and is by far the simplest and cleanest aftermarket EFI system available. It's also the easiest to install and tune. The "Adaptive Learning" feature eliminates the necessity for laptop programming and tuning, except on the most radical engines. By "cleanest", we mean it has minimal wiring showing, so for those street rod, street machine, and custom car enthusiasts who object to other EFI systems because of all the engine clutter with wires running everywhere, this is the system they have been waiting for. 

    It utilizes a wideband O2 sensor, a feature missing from many competitive units. It also has a 2.5 BAR MAP sensor which means you can run up to 20 PSI of boost if you have a supercharger or turbocharger. The fuel pump comes with a combination heat sink and mounting bracket. The EMS (engine management system) mounts directly on the throttle body eliminating a major portion of the wiring required. This means you do not have to cut a hole into the firewall. Additionally the MAP sensor is packaged into the throttle body which means one less component cluttering up your firewall and no vacuum hose needed to run from the firewall to the manifold.
