to vacuum pump, or not to vacuum pump, that is the question?

Put one on it, that throwup looking stuff (water and oil mixed) under your valve covers will be gone. I also get the motor hot 200 or so before I shut it down in the trailer and remove the oil filler caps so it can boil and any extra moisture out of it. I would not want any more than 10-12" of vacuum at the finishline or you will have lower end problems. (wrist pins and bearings) Put a gauge on it and make sure you are not going over, allot of engine builders have had comebacks since vacuum pumps because of people trying to run to much vacuum or running the car without a gauge. Hope this helps, Mike
