I'm thinking I will be fine but just wondering you guys take. The 95 I bought about 6 months ago I have been fiddling around with it here and there fixing some things and the last thing I did was flush it real good and put in a 180 thermostat. It is doing much much better. I just put in straight water just for testing purposes but will put antifreeze in shortly before fall probably. I don't drive the car much at all. Since I have water in the whole system right now and 50/50 mixture is really all you need, especially in SC, I'm thinking I should be fine just draining the radiator and the jug and just filling half the radiator with antifreeze and fill the jug to the hot line with antifreeze. I'm thinking that should provide close to a 50/50 mixture. I have probably ran my other car always sometime around 50/50 or maybe even a little less antifreeze for years with no problems. I do know that too much antifreeze though is not good; too much vs less water that is. The 302 motor will come out probably sometime next year and get sold as I get ready to do my 351.
