As old-school muscle and new-school technology continue to meld, the next step in the movement of electronic engine control is electronic timing control. Fuel injection is great, but who wants to hover over an engine with a timing light, gently coaxing a worn distributor and hoping to find the sweet spot? FAST offers a wide range of EFI products, so it’s only natural that they can also fill the need when it comes to accurate, EFI-compatible timing control.
FAST XDi Race EFI distributors are a recent addition for those with EFI who require absolute precision and adjustability from their timing system. By ditching the common magnetic pickup and replacing it with a high-precision optical trigger, the XDi Race EFI distributor perfectly lends itself to high-RPM, high-power EFI applications.
It’s accurate to ± ½-degree so you get dead-on timing, even as you spin that small block up past 7,000 RPM. Signal to the distributor must be fed via crank trigger to ensure all-around precision. The housing is billet aluminum and home to a ground stainless steel shaft, precision bearings, and a high-quality rotor. Shaft end-play can wreak havoc on consistent timing, but isn’t a concern with this hand-assembled piece.
Chrysler applications include 273-360 LA small blocks (1000-1810EFI for large cap, 1000-1811EFI for small cap), 383-400 B big blocks (1000-1812EFI, small cap), and 426-440 RB big blocks (1000-1813EFI, small cap). The small cap diameter is 4-3/16” while the large cap measures 4-3/8”. Either one will be black and have male spark plug wire attachments. Visit FAST or call (877) 334-8355 for more information.
