New 460 in 76f250 timing problems!!

I put a new comp 292 cam in my 460. The cam dowl was at 6 o'clock my crank gesr, keyway and dot was at 12 o'clock. I put cylinder 1 at TDC. And dropped the distributor in facing the driver side firewall and all the plugs are in the correct order. She starts and runs like ****. Then blows and backfired through the carb and exhaust. Please help

There are two times #1 piston is at TDC - once on the compression stroke and another on the exhaust stroke. Are you sure you had #1 at TDC on the compression stroke and the rotor pointing at or just past #1 cylinder?

That's wrong.... Dots line up together like in this pic.
