I did change the coolant, oil and filter, had the carb rebuilt, blew out the fuel lines, replaced the fuel and water pump, but your right I didnt do anything to this poor ol 235. Today I pulled the head and found that the pistons were hitting the intake valves. Everything was filthy and there was heavy build up everywhere. I was planning on upgrading the drivetrain anyways, its just going to have to happen sooner then later..
