I honestly think it was a great idea at the time so many years ago. If I had one laying here I wouldn't be afraid to use it. Heck I'm still holding on to a few of my old 286 duration @.050 750 lift roller cams that we stepped up to after running that cam. They didn't require the CRAZY spring pressure that we run on cams now and our parts lasted forever.
