Trev, we (Jeff and I) were clipping along at a pretty good pace going up and down that mountain. That 21 stud bored out to a whopping 0.030" over 3-1/16" can run right up there with the big dogs
. That was my second run over that same mountain so I was already aware of some of those sharp turns. Maybe Jeff had his toe on the accelerator or was pulling on that hand throttle when I wasen't looking
.
Anyway, to be honest, I don't remember exactly what my engine temperatures were on that perticular run. I believe in general, on the way out and back, the temperature gauge stayed pretty consistently in the 180-190° F range until I started climbing the higher elevations. During those runs while assending I had some max temperatures in the 200-210 ° F range until I started descending from the peak. Then it would cool down quickly and level out again at ~ 180°. I have Skip Haney pumps in the heads and his overflow check valve, plus a good radiator cap with seal that is allowing the system to run at 3-4 psi. I am also running original can/sleeve style thermostats mounted in center of upper hoses.Worked well for me for over 7k miles on the tour.
