The only EFI system built from the ground up for Big Block and Small Block Chevy.
Every other system makes you adapt. Our System was engineered specifically for the BBC and SBC — eliminating the distributor, protecting your sensors, and delivering a crank and cam signal more accurate and reliable than anything else available.
Innovation 01
Distributor eliminated.
The distributor is gone. The Cyriously Slick system replaces it entirely with a precision crank and cam sensing solution — cleaner, more accurate, and built for the demands of modern engine management your BBC and SBC.
Innovation 02
No external sensors to damage.
External crank sensor kits are exposed, fragile, and a failure point waiting to happen. Our system eliminates that risk entirely — sensors are protected by design, not by luck.
Innovation 03
Signal accuracy that changes everything.
Crank and cam signal quality determines how well your engine management system can do its job. Ours delivers an extremely accurate, reliable signal — the foundation every other component in the system depends on.
01 — Timing & Sensing
Patent PendingBBC Crank & Cam Sensor Kit
This is the component that makes the entire system possible — and the one no one else has built for the Big Block Chevy.
Engineered to eliminate the distributor and replace external crank sensor kits that are vulnerable to heat, vibration, and impact damage. The result is an extremely accurate, reliable crank and cam signal that your EFI system can actually depend on — under street conditions, strip conditions, or full race loads. Available for both carbureted and EFI setups, making it the right foundation whether you're converting or building fresh.
