ok, so i went to empty my radiator (when installing my superchargerer) and it came out brown? (when i put it in, and it was green lol). Now i dont think it is oil, because it is not puddling up since oil and water dont mix, so i wasthinking possible it was rust from the block?
any suggestions? i will be doing a flush once im done with the install

calcium build up rust scale ect ect, flush it when done as you stated

no, not really, mine was the same after sitting for 4 years, stuck a gardenhose in the inlet hose, and disconnected the return hose and ran it till the water came out clear, then I used a few gallons of distilled water to flush the tap water, then added a 50/50 mix of green coolant and distilled water

I have seen alot of 302's that are very rusty. My mom had a towncar with a 302 and we flushed and flushed that thing and we never got it all out. I saw a tech tip in hotrod that said vinegar and water would clean a block up.

no , just gp buy a prestone flush kit and flush it well
