Review: Valve Springs for LS3 1.8 Rocker Arm Upgrade - I installed the Pac Racing valve springs on my 2011 Corvette Grand Sport (LS3) when I replaced the stock 1.7:1 rocker arms with a set of Comp Cams 1.8:1 Ultra Pro Magnum rockers. I've logged about 1000 miles since the installation and the engine behaves all the way to 6500 RPM. I bought these springs based on recommendation by others running this combination and they seem to be a good match.
Review: found the real issue - Had about 3 hours of run time and possibly 8 miles running great on a fresh 5.3 heard a pop. Clatter boom catastrophic damage thanks to a broken spring. update after more research the issue wasn't the springs it was the head shop.
