Oil primed and oil pressure reads alright. Have been cranking on it all day. It spits and sputters but never starts. Have pulled the distributor out and retimed it. If I turn the distributor back I get a loud backfire so I assume I'm getting fire. Working the throttle I can see gas going in. The distributor is a HEI that I hooked up to iginition hot so I could have 12 volts. I had this engine running before. The last thing I did was change the water pump but I don't see how this would affect anything.
