Rising from the depths.... Put a NUCLEAR MISSILE in your N/A high-effort 7.3 Godzilla with the latest grind from BTR! We use proprietary in-house designed lobes and our own Landis LT grinding machines and REM polish process to bring you another killer cam from BTR. Spintron tested, dyno validated, this camshaft will seriously kick your high-effort 7.3 build in the pants! Expect 130+ HP and 60+ FT/LBS gains over stock, and 18+ HP and 10+ FT/LBS and more RPM range than the legendary BTR Godzilla Truck Norris!

Due to tight valve clearance, and the extra RPM capability, we recommend only using this camshaft with a quality aftermarket rod & piston combination.
