GPI LS7 Cam - Thump '24 with 8620 Hardened Core Upgrade (2010 - 2015 Camaro Z/28 | 2014 - 2019 C7 Corvette Z06) - gpi-ls7-cam
Premium 8620-Hardened LS7 Camshaft for Maximum Durability
The GPI Thump '24 LS7 Cam with 8620 Hardened Core Upgrade delivers the same aggressive performance and proven power gains as the standard Thump '24 - now with significantly enhanced wear resistance and longevity. Built for serious enthusiasts running hard on the street or track, the 8620 upgrade ensures exceptional durability under high-RPM, high-spring-pressure conditions.
Please note: This is a high-lift, 3-bolt LS7 camshaft. It requires .660? dual valve springs and hardened pushrods for proper installation and reliability.
Why the 8620 Hardened Core Upgrade?
GPI's 8620 hardening process enhances the surface strength of each cam lobe while maintaining the core ductility needed to absorb valvetrain shock loads. The result is a stronger, more durable camshaft that withstands extended high-RPM operation and aggressive ramp designs. For LS7 owners demanding the longest possible service life in demanding conditions, the 8620 option offers a superior advantage.
Industry-Leading LS7 Camshaft Engineering
GPI LS7 cams are widely regarded as the benchmark for 5th Gen Camaro Z/28 and C7 Corvette Z06 builds. Their broad torque curve, high-RPM stability, and compatibility with both naturally aspirated and centrifugal-supercharged setups make them an elite choice for performance-focused drivers.
Designed for NA builds but exceptionally well-suited for centrifugal blowers, the Thump '24 delivers outstanding drivability, strong midrange response, and unmistakable cam character.

The 8620 hardening process creates a tougher, more durable wear surface on the lobes - ideal for high spring pressure and long-term high-RPM use.
Is this camshaft suitable for a future centrifugal supercharger setup?
Yes. Its power curve complements centrifugal blower characteristics extremely well, making it a great NA-now, boost-later cam choice.
