Holley EFI Crank Trigger Kits

Holley's EFI crank trigger kits provide accurate crank speed and position signals to Holley EFI systems in the most demanding, high-horsepower, racing applications. The crank position is measured every 10 degrees instead of every 45 degrees, like standard 4-magnet crank trigger systems. Holley's EFI crank trigger kits feature 1/4 in. thick, billet steel, 36-1 or 60-2 tooth-crank trigger wheels with black zinc oxide finish for superior corrosion resistance and striking good looks Other notable features include: * Crank wheels center off of balancer hubs, eliminating the need for centering rings * All billet, 6061-T6 aluminum sensor mounting brackets with "bright-dipped" black anodized finish and laser-etched Holley EFI logo * Custom 3-wire, ferrous-target, Hall-effect sensors with M12 x 1.0mm threads for finer gap adjustment * Grade 8 and mil-spec mounting hardware

PerTronix Flame-Thrower Race HEI Distributors

Flame-Thrower Race HEI distributors from PerTronix produce 42 percent more energy in the coil, with 46 percent faster spark breakdown time. This allows 48 percent more peak current to reach the spark plug, compared to their Street/Strip HEI distributors. That's an enormous improvement over stock HEIs and most aftermarket HEI distributors. A specially designed vacuum lockout mechanism prevents timing adjustments that change rotor phasing, adversely affecting the burn time and efficient fuel combustion. The rotor plates are TIG-welded to the mechanical advance mechanism, preventing high-rpm distortion and improving mechanical reliability. Each distributor uses a new aluminum housing cast and is machined from a strong, but lightweight A384 alloy. They're supplied with a high-dielectric strength cap with solid brass terminals, a balanced rotor, and a low-resistance center coil brush. Also included are nylon rotor hold-down screws and a factory-installed, high performance mechanical curve kit with precision-machined weights and a center plate. A hardened, machined steel gear is standard, along with an electronic module and coil combination that excels in the 6,000 to 8,500 rpm range. These distributors are great for both Circle Track and drag race applications where factory-type HEI distributors are mandated.
