Well since we are diagnosing engine problems i figured i would throw mine in there. I have a built 454 and a new MSD ignition. Around 3000 rpms it will start to slightly miss, not enough to give any loss of power but it is easily heard. It doesnt happen before 3000 rpm nor under WOT. I dont remember it doing this before the new ignition system so could this be a timing issue. I had the complete MSD ignition systme put in by a mechanic (dont laugh i know how just didnt have time with work and all) and he set the timing for me. He said to try and change the spark plugs which i did (although the plugs only had about 50 miles on them but they looked horrible...maybe because of me repeatily trying to crank it when diagnosing the ignition problem). So put in AutoLite plugs...nothing special... and it still does the same thing. Do i need to get plugs i can gap or what going on here. Thanks Michael
