Shes alive an shes stayin alive!!

I would find out from Milodon where the marks are supposed to line up, then check to see if you are correct. It sounds as if they have the dots both straight up, it will act weird and fart and puke, as some cylinders will fire, and others will be late/early. If you have the marks correct, the only issue can be TDC, (is it on compression: both valves closed) or firing order. Make sure the rotor is going the way you wired it, Big Blocks turn the opposite of Small Blocks because of the distributor being in the front.
