Professor OD now says the 20 to 30K miles should be limit on people using bigsprings and reduced oil flow to the rockers. They also said that crane warrrentys theirs for 100K miles.

I think I still will be replacing my aluminum bodies (proform 130dollar specials) with a set of comp Pro magnums (the rockers are about the only weak link in my motor). I don't want to go through the thing for a 3rd time.

Another thing I noticed was that they said that question was from bill hunter from alice texas. Well, they had another letter from bill hunter from alice in this months OD column. Bill seems to get a lot of time in the summit rag.
