Your timing belt has probably worn out, or broken, and has jumped timing.
It could be your carborator. Check that out. If your using Holley get rid of it. That is complete junk.
The engine is out of time. Have the engine timing checked. It can also be the plug wires are connected incorrectly.
No, it is not. BUT: Starting a car with the exhaust submerged carries other risks. By implication there are other things submerged that could be damaged by water, such as the alternator, HVAC, or transmission. Also, the engine may not start if the starter cannot overcome the water pressure.
First check for fire at any of the sparkplugs and if you have spark then check your fuel pressure and if its not within specs then replace the pump.
Double check, then triple check your firing order. Especially which distributor post is #1. Sounds like you're one off.
Timing is off.
Valve timing off, timing chain jump.
Your car backfires when you need a new transmission,or tune up. How do you know the difference? Simple...if your car backfires then wont start, or wont start and then backfires,you need a transmission. If it backfires, and then starts moments after, you need a tune-up. Glad to help...David

spark plug gap, gas/air mixture on carb.

That is called condensation. When you start the engine the exhaust system/pipes are cold. When the heat from the engine exhaust passes through the exhaust it makes it sweat. That is normal.

Possibly the firing order got messed up.
