1972 Demon 340 engine mods
Compression test shows all cylinders between 140 and 150 psi. Driver side closer to 150, passenger to 140. Before heads swap situation was similar, 120sh on passenger side and also 130 on drivers. Small change for better I guess.
Distributor cap looks seriously oxidated, 5 out of 8 spark plug terminals were green and looked really bad. I used small wire brush on dremel and bring it to decent shape, but also ordered a new cap just in case my cleanup won't be enough. Shame I did not take a photo before, but here is how it looks after cleanup. One cylinder looks the worst of all.
