360 timing ignition woes

First off thank you all for the suggestions I am very happy to say I have resolved my issue, but am ambarressed to say what I found lol. It turns out that my ecu was the problem the whole time, I replaced it and every other ignition/timing part all at once and some how managed to set my crank shaft to top dead center........on the exhaust stroke. Sooooo several sleepless nights and hours in the shop all I needed to do was spin my distributor 180 and all was fixed. What started as a simple parts swap turned into a much bigger ordeal due to me missing a simple step
