Im stumped, It's missing and ticking.

My motor started running a little rough the other day, Kind of like it had a small miss and today on the way home it got worse it started to act like it wanted to cut out at low idle and then sometimes at higher so I had to power brake it (foot on the brake to slow it down so I could rev it higher) about 1/2 mile from my house. So when I got home I checked the timming, carb adj. , cleanned the plugs, the cap, rotor and wire are all less than 2 months old. Everything checked ok so I swapped out the ECU for another, nothing.
I thought that maybe it was the fuel pump and or filter, changed them, bolth had about 8000 miles on them and were new installs when I dropped in the rebuilt 360.
Im getting a weird "ticking" sound when the motor is running, It's very sporatic and has no real rythm to it. The closest thing I can compare it to is if you umplugged a spark plug wire and held it against some metal almost like a zapping sound. It is comming from the passenger side front of the motor and there is no change if I pull the PVC,or pull plug wires one by one all along the pass. side, I made sure that #5 and 7 wires weren't crossing, I can't feel any weird knocking or vibration on the motor, valvecover, timming cover, ect., I haven't found any loose wires, or seen any arc flashes, my oil pressure is normal, and so is the temp. WHAT THE HELL!!!! The only thing that I can think of is a smushed lifter maybe but the "ticking" isn't loud enough and my oil pressure is fine. I need help asap, Im going to be driving a Mazda to work until I figure this out, I don't want to hurt the motor in the scamp. :cussing:
