I’ve decided to try and fix this engine up rather than a full rebuild. Im doing some compression and leak down testing and labeled the cables, but on a whim decided to look up the correct firing order. This doesn’t look like what I’m finding online. What do you think?
It’s a 69 f250 with an FE engine, supposedly a 390.
