Not Ranked
My guess is a a big, very-high lift cam. Detroit engineers probably didn't envision running much over .600 lift cams back in the 50s and 60s. Hard to avoid some side load even with all the latest roller rockers and everything. Running big performance stuff has got to increase wear and maintenance.
Or I could be wrong.
Edit - yep, I was wrong. Should have waited.
