Granatelli 1.7 Rocker arms Hey guys just started posting on this board ...I'm Chris and I work at GMS, just thought if you didn’t mind reading a quick paragraph id tell you a little about our Rocker arms. 1.7 ratios obviously, precision-engineered out of High Strength 7071 aircraft alloy. Fits under stock valve covers, and are designed for shaft mounting meaning more stability and reliability in high rpm situations. An 8%-11% hp gain is realized as well as a slight improvement in fuel mileage.
Our Rockers will work with MOST aftermarket valve springs and feature an oil passage in the front of each arm for cooling purposes... Guaranteed for a year from faulty workmanship or materials, including the aluminum arms themselves, the alloy steel trunions and shafts, and posilok nuts.. Thanks for taking the time to read my post and if you have any questions feel free to call or shoot me a reply on here ....

How much weight do these rockers have over the valve compared to stock? They look heavy.
