for some reason my mileage suddenly dropped drastically, like from 420 miles per tank to like 320 miles with no different driving on my side. I felt this at first just a little before I hydrolocked the engine. After I got the car running again I could see well that mileage suffered, but I can't say for sure the hydrolock was the cause because I felt it before it also. I think it also used to pull better (well, as much as a stock 420a can pull anyway). Idle is ok when warmed, kinda rough when cold.

Any ideas what I should be checking, cause I'm afraid I'll just start throwing new parts at it at random.

Tonight I'll do a compression check.
