yeah i noticed that people run them down alot but me my mom and my uncle have one and they are all good engines except for the one in my 79 and it was un til the fuel pump got screwed up and it has got gas in the oil and everyone that i talk to about it says that the cam is out and stuff so i guess i will get another 305 i found one pretty cheap these engines if you run them right you can put alot of miles on them
