Default Re: Roller Rockers in Stock

Furthermore...


Chris Hill stated:
"The parts still broke with bearing steel. Then we changed the design of our valvetrain to lessen the impact loads, we could use the original Stainless steel material. The issue was not the material of the part or heat treatment, it was just a bad design".

Jeff ask's:
So you had failure with stainless rockers, developed a whizz-bang cryptonite rocker to no avail, then fixed the cam lobe and then the original stainless rocker stopped failing. Is this correct? So a better cam lobe solved the problem and therefore your confident that a standard Speed-Pro SBC stamped rocker available from AutoZone will get the job done on the lobe you and your crew developed under competition useage (burnouts. various loads, possible missed shifts, etc.)
So my big question is, what type of cam lobe are you testing against? Is this a NHRA Stocker lobe with approximately .450" lift (which I'm guessing may be an average) with duration and ramp designs that will allow the engine to be competitive? Or are you talking about a bracket-style, maybe even street / strip style cam lobe that is much less aggressive than the Stocker lobe?
