318 problems

I have a 318 LA in my 65 Coronet. Back in June we got a ton of rain and I was driving the car. I made it home but water got in the distributor and since then I've been fighting problems with that distrutor and recently replaced it. So I installed the new distributor, had to pull it back out and the shaft was very thick and stuck in the oil pump/ Cam gear. The gear dropped back down and I've lined it up parallel to the cam but it won't start. I have spark at the #1 plug wire but it still won't start.
Any advice is greatly appreciated in advance.
Thank you.
