Description
The TSP SmartFire Performance HEI Distributor for Chevrolet SBC and BBC engines combines the convenience of a self-contained large-cap HEI ignition system with advanced app-controlled ignition technology. Designed for carbureted Gen. I Chevrolet small block and Mark IV big block V8 applications, SBC fitment includes 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400 CID engines, while BBC fitment covers 396, 402, 427, and 454 CID standard-deck engines. The integrated HEI design combines the ignition coil, module, cap, and rotor into a single unit, requiring no external coil or ignition box.
The 65,000-volt internal HEI coil provides reliable ignition performance, while SmartFire's software-controlled advance eliminates traditional mechanical springs and weights. Through the TSP SmartFire app, users can customize ignition timing curves, adjust the 2,000–8,000 RPM rev limiter, and save multiple tuning profiles directly from their phone. Live monitoring displays engine RPM, battery voltage, module temperature, and ignition timing, with session logging for later review or sharing with a tuner.
Available with Red or Black distributor caps, this distributor fits a wide range of carbureted Chevy V8 applications, including Camaro, Chevelle, Nova, Corvette, El Camino, Monte Carlo, Malibu, Impala, C10, C20, K-series trucks, Blazer, Suburban, and their GMC equivalents. From classic restorations to high-performance street builds, SmartFire combines the familiar simplicity of HEI installation with the precision and flexibility of modern digital ignition control.
Modern Ignition Control for Classic Chevy V8 Engines
The Chevrolet Gen. I small block and Mark IV big block are among the most widely produced and modified American V8 engine families. The Gen. I SBC powered Chevrolet and GMC vehicles across decades of production, while the Mark IV BBC became a staple of high-performance muscle cars and trucks. SmartFire brings these classic engines into the modern era with programmable ignition advance, wireless app connectivity, and real-time performance monitoring. Instead of physically changing springs and bushings to adjust ignition timing, users can fine-tune the advance curve electronically and save multiple configurations for different driving conditions.
Performance Benefit
SmartFire replaces traditional mechanical advance with precise, software-controlled ignition timing that can be adjusted directly from your phone. The programmable 2,000–8,000 RPM rev limiter provides additional engine protection, while live monitoring and ignition session logging offer valuable insight into engine operation. Whether tuning a mild 350 street engine or a high-performance 454, multiple saved ignition profiles make it easy to optimize timing for different setups without distributor disassembly or mechanical adjustments. Combined with its integrated 65,000-volt coil and self-contained HEI design, SmartFire delivers modern ignition control with the straightforward installation of a classic HEI distributor.
