Truth about roller cams.... BEFORE you make the switch......

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!
A fellow Hot Rodder friend is rebuilding his 528 Hemi and is installing a Crower billet over .600 lift solid lift cam. He has also installed the coated steel distributor gear from Hughes.
We will see if it works in a couple months when he gets the engine installed. It wont take long after he gets it running because the man is a driving fool.
