Actually there is a gain over the stamped steel rockers. I proved it years ago changed my stamped steel rockers and shaft assemblies at the track and put on NOS 70 assemblies. Picked up .10 sec if my memory serves me. ou: :beer
John: Are you going to bid on these? If you are I will leave it alone. If not I think I will bid on them. Let me know because I don't want to run them up if another board member is going after them. Marty
I would be suspisious of the alum rockers/shafts. If wear did start it was usually not bad due to the aluminum on steel wear issues. Some did last ok IF oil was changed regularly. Any sludge in the pushrods and they starved for oil. The NOS ones that I used were fine even with pretty high spring pressues but they were over maintained.
