    you guys suck, it should be at least 120 and those wires and cap are junk.

    105 is a little on the low side. Did you do the test with the engine warm and the throttle blade at WOT? My compression on my S/C is 118-120. I consider that about the lower side of a healthy engine. Not to say that you motor is crap, but the numbers are by no means good.

    Agreed, healthy is 130+ range. How is the timing? Timing slightly off makes for a slug...

    130-140 is for a new or in good shape engine.

    If all your cylinders are even, then your fine, but if you have say 120 in 3 then 105 in one cylinder, you have a problem.

    Are you 1000% your cam and ig timing is bang on? whats your idle vacuum?
