Anyone put 100k+ miles on full roller rockers?

The only time I know of GM using full rollers was the crane gold rockers in the LT4 corvette engines back in the 90's, but I don't know anyone who's put miles on those cars. Has anyone used aftermarket full rollers on a daily driver and put real miles on them?

I have not run them that long. But one thing to consider is that steel has longer fatigue life than aluminum. They taught us in school that if the stresses are low enough steel can have "infinite fatigue life" whereas with aluminum you can't.

No idea how many miles are on these, but I'd guess a lot. This engine was ran naturally aspirated for years in a few different cars and now it's going into my 68 with a blower on it. No appreciable wear on the rockers. They are Lunati 1.6:1 I believe, although they were purchased around 20 years ago so I'm not 100% positive.

Re: Anyone put 100k+ miles on full roller rockers?

Would you consider 10,000 passes at the track turning 7000 rpm a product test with no failures ? Which one would you consider the most, 10,000 passes at 7000 rpm or 100,000 miles on the road ? Are you planning on buying these roller rockers which leads to asking such a question ? Or you bored with nothing else to ask ? Call the product test hotline and ask them to send the hard copy of the product integrity test results which may assist you in getting your answer.
