Pertronix Flame-Thrower HEI distributor Ford 221/302, with vacuüm advance.

STREET / STRIP HEI distributors Our HEI distributors are built from the ground up with all new components. We have engineered a special high energy module and coil combination that operates without misfires beyond 7500 RPM. That's nearly 3000 RPM higher than most stock HEI distributors. Flame-Thrower HEI distributor produce 67% more energy with a 45% faster spark breakdown time when compared to the stock HEI. This means twice the energy to the spark plugs. Our tests show that with these improvements wider plug gaps can be used resulting in an increasing flame kernel growth for more efficient combustion.

• New lightweight aluminum alloy housing.
• Aligned and honed high quality bronze sintered bushings for reduced friction and extended life.
• Centerless ground corrosion resistant shaft reduces friction and provides concentric operation.
• Distributor gear is ground to exact tolerances for tighter mesh with camshaft. (Bronze distributor gear available)
• High dielectric strength cap with brass terminals and low resistance center coil brush.
• Balanced rotor with nylon screws prevent arcing and reduce vibration at high RPMs.
• Adjustable vacuum advance canister and high performance advance curve.
• Precision machined chromoly advance weights and center plate eliminate erratic timing.
• Meets stringent automobile susceptibility, vibration and shock requirements
