Did 318 intake, fires but won't start

No dice on the jumper wire. I'm beginning to think it's a firing order issue. I never removed the wires from the cap or the cap from the distributor. I also never removed the distributor. I marked the number one tower and wire before removing the wires from the spark plugs. Firing order 1-8-4-3-6-5-7-2 correct? I gave it some gas while cranking and it backfired through the carb.
