Here we go again... Anyone that drove cars back then knew normal operating temp was(and still is) 210 w/a 195 stat. Don't believe me, do a search for test drive articles from that era. No one got concerned unless they went higher then 225-230.
From 76-79 my FB w/11.5 cr, 255/263 sft, and 195 stat ran 220 w/o any probs. In fact the fastest times at drag strip where at this temp. Factory shroud, factory 4 blade fixed fan, standard radiator, and NO upper covers. Did have lower valance.
