Get More Horsepower Out of Your LS, Gen III Hemi, or Ford Godzilla Engine with a Callies Street Series Camshaft

Callies is probably better known for their killer crankshafts and connecting rods, but they also make some equally killer camshafts. Here's why.

Callies Street Series hydraulic roller camshafts for GM LS, Ford 7.3L Godzilla, and Chrysler Gen III Hemi are made from billet steel cores that are fully machined and heat-treated in their Ohio-based facility. They’re ground on the latest Landis CNC grinders; cam lobe geometry is inspected with ADCOLE precision gauge machines and Jenoptik laser scanners. Those fancy-schmancy machines ensure the Street Series Camshaft profiles are consistently accurate and provide the performance Callies says they will. You can see gains of up to 90 horsepower naturally aspirated and up to 180 horsepower on turbo and supercharged engines depending on the type and parts combination.

Callies Street Series Camshafts are available for naturally aspirated, turbocharged, and supercharged engines.
