Check the cap and rotor. Make sure the 3 wire connector is on. Make sure the power wire is in the right spot and not the tach spot in the cap

When I took the old one apart the red wire was on the right and the yellow wire was on the left, so I put them in that same placement on the new one. If thats what your trying to tell me, would I be looking at points-type ignition or HEI ignition?

80 should be HEI

look on top of the cap. They will be marked. Red is power wire

I think I may have found my problem, I was going by points-type ignition because when I took it off wire #1 was on the left side of the tach cap I was sure, if the plug wires were in the wrong order could that be the problem? I know the firing order around the distributor is right, it could just be in the wrong spots?
