Trying to get my motor close before I take it out but I think I should have a little more vacuum (maybe not). I have a Lunati Hyd Roller cam in my 498 right now, I don't have the card with me but the seat is around 310* and the .050 is about 255*. I knew the vacuum was going to be low so I installed a hydo boost brake system but at idle I am about 6 inches of vacuum. I put a 3.5 power valve in my carb and have 4 corner idle screws as set it as best I could. I have the timing set at 14* btdc and idle at about 1k. Runs great, idle sounds good, no sign of leaks etc. Am I missing something or is this ok? I am going to get a O2 sensor from Mike (Wolfplace) as soon as I can afford it, but am I in the ballpark for now or should I be looking for a problem?
