Ya that's the one aar...but I think I lost you on the wire hook up I don't think I have any of those color wires my dizzy has a red nd blk nd a blue nd blk I'd have to double check on wat my ign box wires are...and ya it runs good below 4500 then its everywhere nd so is the timing mark I know the msd does multi spark below 3000 so I'm sure I'm getting spark scatter I just have to get it timed right nd the polarity right nd see if it still does it
