 200-ish. That engine should run 200 at tops. What type of engine do you think is dangerous? 220 or above. I wouldn't go any hotter than that. But, really, you would like that one to run somewhere around 200 in that era. Do you think 200 would be okay? Because, yeah, now, yesterday, like, my dad was just getting paranoid once it got to, like, 195.
