Post #3, LOL

OK you did check dist 180 off? I guess. Checked the timing chain?

I'm not sure about the condition

Grab the crank pulley or use a breaker bar with appropriate socket, and move the pulley back & forth (CW/CCW) and measure the distance. The factory specs travel to no more than 1/8", otherwise replace the timing set.

hello I have a 66 charger with a 77 440 in it I just got it been sitting for who knows how long put plugs wires ready to run distributor ect. It backfire out the carb and exhaust im think maybe some stuck valves but just looking at some ideas it sat with no carb on i got it free and soaked with some marvel put a 90s dakota starter amd it turns over really good just cant get it to actually bust off and run any help would be appreciated

Sounds like timing to me just start loosen off dizzy twist till it runs better Cheers Steve

We have worked on a couple that would do as described. Timing off, firing order wrong, 180 off, backwards on firing order. The biggest pain is Jumped timing chain. I can remember two times where one minute it was running. Shut it off and the next time wouldn't start and just popped through the carb...the cam timing was so far off it want not going to run. They usually will run 180 off...just dont have your head above the carb if you want to keep your eyebrows.

A compression test will tell you the engine condition.

Great place to start.
