Running Issues

Basically stk 360. Mild 260/.440” cam.
Made up of all diff parts. And I have changed a lot of stuff around trying to fix this, - so I guess I probably introduced new problems.
This distributor. A reman. Points open before rotor meet the post. About 1/4” before getting to it.
& I think advance makes it worse.
Rad good, then Ran bad, now won’t run at all. Wants to start, but wont fire up and run.
Has banged out the exhaust a couple times and the wife comes out the house to see if I had shot myself.
- she was disappointed.
Was thinkin to ignore the distributor, and checking valve timing next.
