The Stage 3 cam is designed for crate engines and engine swaps into lighter cars or trucks for best overall performance. This cam will produce well over 600 horsepower on pump gas! Awesome power can be expected from 5,000 to 6,700 RPM with the valve spring kit (#7230GCS-KIT) and a phaser limiter (#5473). Testing with the 5473 phaser limiter kit resulted in nearly 100 HP and 25 lb-ft over stock. This much horsepower will make even Godzilla fly.
