Water in Engine

Hi folks! I picked up a gem of a car. Its a 65 Signet with a 273 auto 8 3/4 rear Big bolt pattern all the way around. Body is in pretty good condition. It was in an accident, I have most of the sheet metal.

Bad news is the guy left the hood off and it rained pretty bad, for a while there was a good amount of fresh water in the motor, no rusting any where except a minor spot that came clean with a hone.

Motor turns over freely, I soaked the cylinders with Marvel for a couple days. Right now the intake and heads are off of it. Everything looks good. When we drained the oil there was no traces of rust or anything. In fact the water was crystal clear.

So I am wondering if its worth it to put it back together to see if its ok or pull it out and do the whole rebuild.

Its my sons car so he is learing, I am in the Navy and time is more important than money.

Any thoughts??
