This is an serious performance camshaft with an aggressive idle! It is a great choice for those looking for every last ounce of horsepower from their LS7 engine.
TSP's new and improved LS7 Stage 4.2 camshaft has taken what was already a proven camshaft and made it even better! With countless hours of testing on a SuperFlow 902 engine dyno, they have revised all of their LS7 camshafts for better power everywhere in the RPM band! All camshafts were designed using a factory GM 7.0L LS7 engine with no other internal changes.
This camshaft features custom-ground lobes specifically designed for the LS7. These lobes not only make great power throughout the entire RPM band, but they are also much more stable. This equates to a quieter, longer lasting valvetrain compared to most other comparable camshafts. All TSP camshafts are 100% developed, ground, and polished in-house using state-of-the-art Landis CNC camshaft grinders!
