John,
I roll into the burnout box around 160-165 degrees no water pump or fan on at all. I usually gain 5-10 degrees during a 1/4 mile run, once i get to the return road I will flip the fan/water pump on. If it losing temp during a run its usually a good sign of being rich and you should lower the jets.
If the motor has good parts in it shift it 7200-7400. My motor liked 32 degree's timing on the dyno and seems to be the sweet spot on the track also, that is something you will have to play with a little to find out the right combo.

Now most 632 ci motor should be on gas, you are to the point of alky will not be as far or as good as a good gas set up. Take that for what its worth, I am a diehard alky user and wouldnt run it on anything over 598ci
