Sorry, I was lucky enough to drive a 68 B body Hemi car. Never built one or tuned one. You are the expert there. Apparently the author of the article has not. I was just sharing some information that seemed to come from a reliable source. Apparently I was misinformed. I will just stop posting information of any sort. I don't want to look stupid and spread incorrect information. I could say more but I think I will just shut up while I am ahead.
