I mean no disrespect but do you have dyno figures to support night and day. The engine in question is an "OEM 3.0SC". I can put fresh plugs in my 2.2S and set dwell and timing and get what I would consider night and day improvements. The other part of the discussion, cost, Jeff said it adds 250-300 to a complete head rebuild? That is just the machine work, then you have the ignition system and wires. I went with a 12 pin dizzy $1500, Wires, I am making mine using magnecor ends $235 plus the wire another $150, two coils $50 each +10 each brackets, twin MSD boxes $235 each. I am sure I have missed something including the pistons that required the twin plugs to start with and some odds and ends. My point is, 250-300 is like pissin in the wind compared to the overall cost of twin plugging. Are you machining the lower covers now also? The logic just doesn't seem to be there because you are going to do a teardown again when the time comes. Use the 250-300 and take your wife out to a few nice restaurants. Do the twin plugs when you need it. You guys need to understand that I am a CPA. In some circles that means a bean counter and in others that means Constant Pain in the A$$.
