1974 D300 360 fresh rebuild will not start
Compression, Ignition and Fuel
In that order, no compression nothing else matters.
Google your questions, there is a lot of useful information on the internet. Also youtube videos are good at explaining things too. I use them all the time.
Now, why didn't I think of google??? -Not to be a smart ***...- There isn't a video on youtube I haven't watched, or a post on this forum I haven't read. I'm reaching out to the wealth of knowledge here exactly because I've been lurking for years and have a lot of respect for the intuition and knowledge of the posters here. I am by no means unfamiliar with mechanical theory, and like to think I'm actually even pretty savvy on my 360 in specific. That being said, I'm beyond stumped, obviously.
Adding oil to the cylinders does absolutely nothing for my compression. Each cylinder is at the exact same 59 PSI. I've dumped fresh fuel right down the carb to no effect. It had been sitting for a while with about a gallon in the tank, and then topped it off with another 5 ethanol free, in case it was feeling old n funky.
-And correction, cam at 12, crank at 6 :P Also, if my cam were off by a tooth, then I should have valve blowby during a leak down test at TDC, correct? All I hear is through the rings. When cranking over by hand, I can hear the valves begin to open/air escape through their respective valves.
I DO have spark, using a spark tester currently not rigging a gap. It shows a fairly bright light, and testing the same light against my 76 Ford, it's about the same/brighter on the Dodge. Not sure about a fat blue spark though :/
