I have here a set of Shanon's Engineering 1.75:1 ratio stainless steel, reduced weight, shaft mount roller rockers, They have been tested for 24hrs continuous use and performed beautifully. When i bought them, they still had flashing left over from the investment casting process. mainly in the pushrods cups. I spend alot of time cleaning these out and deburring everything. i will sell the set outright for 175.00 shipped, and will trade for performance parts of equal value.
the second pictures is a visual comparison next to a set of stock oem rockers.
on a factory camshaft, these will give you a more aggressive ramp rate and approximately .020'' more lift.
