Great top end for brutal torque
We used this kit on Top Secret Speed Project 3. 10.5:1 383 with a Howard's 110245-12 cam. The engine made 465ft/lb@3800 and 425hp@5400. Excellent torque numbers for a cruiser or heavy pick up. We will use this kit in the future for sure. Brodix quality and support is second to none!
