With great performance and availability, the GM LS (LS1, -2, -6, -7) engines are an increasingly popular choice for retro-fit street rod
and muscle car applications. In stock form, these engines are decent performers but they have much more to offer. And now with the
Thumpr™ GM LS Cams you can have all the efficiencies delivered by this modern engine platform with a head turning “old school” hot
rod sound and serious performance to back it up. The new Thumpr™ GM LS Cams are compatible with both carbureted and re-tuned
electronic fuel injection (EFI) engines and do not sacrifice anything in durability or street manners.

* In EFI applications, computer tuning is required.

  • Designed for EFI (tuning required) & carbureted 1997-2008
    GM LS (LS1, -2, -6, -7) engines; excellent street manners

  • Early intake valve opening and long exhaust duration create
    optimum overlap for a powerful, hard-hitting exhaust sound
