When it comes to selecting the right camshaft for the late-model G3 Hemi build the first name that immediately springs to mind might not be Callies Performance Products. Certainly Callies has earned its stripes with its unmatched crankshafts and connecting rods, and even Callies’ sister company Energy Manufacturing which produces the cast iron G2 Hemi blocks sold through Mopar’s revived Direct Connection performance catalog – but many simply don’t know that Callies is a premier camshaft manufacturer that offers several entries for the modern Hemi.

First, a little about their process: Callies’ camshafts are machined and heat-treated entirely in-house from carburized and hardened 8620 steel cores. Each cam is produced to AMS 2301 (AQ) standards, ground with the latest Landis CNC technology and checked using ADCOLE and Jenoptik inspection standards. Callies’ fully finished camshafts are guaranteed for metallurgical consistency; whether its a Fully Finished, Indurocore or a Titan Tool Steel camshaft. And Callies’ Cam Research Lab evaluates valvetrain stability up to 11,000 RPM.

While yes, Callies certainly has crankshafts for the Gen III Hemi (you’ll want to check out their offerings here) if you’re looking at just ramping up the overall streetability of your modern Hemi, check out this snapshot at their optional bumpsticks that we’ve included below. Whether you’re looking for a little more low-end grunt or some serious top end racing performance, Callies has the grind that your Hemi will love. Then go and pick out some new connecting rods and a stroker crank. You won’t be sorry!
