Quadrajet EFI Master Kit

The Holley Sniper EFI Quadrajet Master Kit GLD replaces a Rochester Quadrajet 4-barrel carburettor with a self-tuning throttle body. It targets owners of classic V8 engines who want electronic fuel injection without fabricating a custom intake manifold. The kit bolts to the stock Quadrajet flange and includes a complete fuel system.

3.500 in. Touchscreen Control

A 3.500 in. handheld touchscreen provides the calibration interface for initial setup and live data monitoring. It handles fuel-table learning, idle-quality adjustments and basic sensor diagnostics. The screen cannot drive advanced logging, multi-channel wideband control or standalone ECU functions beyond the Sniper firmware scope.

Classic Gold Finish Hardware

The gold-anodised throttle body and brackets deliver a period-correct appearance for show-oriented builds. Included fuel-system components — pump, filter, regulator and lines — are sized for the Sniper unit only. Builders needing higher flow rates, returnless plumbing or forced-induction support must source additional parts separately.
