ATI balancer , I'm going to guess you didn't get it with a 3 bolt GM pattern?

I wonder if you have something else going on that is causing it to run hot?


Yeah, it's a bit much but I'm running quite a bit of compression (again, not helping) but the motor has so little time on it & it's always been like this, I'm thinking I just fell short in planning my cooling system. A buddy of mine who is MUCH more mechanically inclined (actually he's an ASE mechanic & teacher) says it's okay & as I said, it pulls real well when I do drive it.
All this has got me thinking that maybe I should back off the timing, TRIPLE check everything and see what comes up. It wouldn't be the first time anyone's overlooked something and chased the wrong "problem"
