99 problems and a Ford ain't one.

At what point did I refuse a solution? Just because I rejected the idea of a return line? My car ran fine for years without one. I never once disagreed with anyone's comments so far. I aporeciate everyone's advice. I am in 100% agreement that the motor is trashed and needs to come out. Honestly, I think I am just going to take the engine to a scrap yard and put a 383 in it like it should have anyways. This 340 has caused me nothing but misery.

I’m not sure how this is the 340’s fault?

Did you actually VERIFY that you have that much fuel pressure? I’m doubting you do. That needs to be cleared up first.

If when you killed the original cam you didn’t pull the engine and complete disassemble and clean it, then that’s why this time it’s dead. You can’t kill a lobe and think the filter will get all the crap going through the engine. Most likely, the filter plugged rather quickly and then just bypassed all the oil right into the engine.

So address the fuel pressure issue first, then pull the engine, clean it up, replace the parts you killed and put it back together.

The fact that it’s a 340 has zero relevance to anything except what you superimpose on it.
