I never heard that but I have heard that the stockintermediate shaft should be upgraded. Not so much the oil pump. Where did you read this?

And along this line, I've read a 100 roller cam suggestions to people building motors, even newbies. And I've never read on this site where somebody said "be sure and buy that new hardened gear". Maybe it has, and maybe somebody asked and had it answered, but it's not the general remark when somebody suggest a roller cam. Thus, I'm sounding the horn!

Like I mentioned above, the catalogs have the warnings. Phone calls I have made have always had the tech make the mention of upgraded parts needed. As in must have needed parts.
