Thanks Leon...what you said about Head port readings verses Intake port readings makes total sense, especially considering that the heads/block are what we are trying to protect (as opposed to the Intake)...but how much difference should we expect? If I was a little more "obsessed " with knowing that answer, I'd swap locations of the sender bulb and electric sending unit...then record those results...but I just got everything buttoned-up so nice, and what I really want to know is whether or not I am close to doing damage when the factory gauge is maxed out?

So if 210 isn't out of line for a big block...when should I start to worry?
