White Smoke
I have 502 Dart Block Supercharged Engines with 250 B&M Blowers with 7 lbs of boost. 605hp at 5500rpm. At startup, my starboard engine blows out a cloud of white smoke. When cruising, I can see a little white smoke, but not much. This started happening after I ran my engines hard for about 10 seconds and got my oil temp to 255-260 degrees. What are the possible things that could be wrong?

I would also check the exhaust risers for the possibility of water leakage back into the engine.

BTW, if it only took 10 seconds to raise your oil temp to 260*, you have an engine oil temp issue. You may need to add alarger oil cooler, especially with the supercharger. What did the oil pressure go down to when this happened?

I know I need larger oil coolers. After about 10 miles of cruising at 3000rpm, my oil temp goes to about 230 degrees. I usually set her down and let her cool off before going on plane. My water temp stays the same, around 105 degrees. I have not noticed any water in the oil yet, but that could change over time. Did not notice oil pressure drop, but they don't work well either, wrong sender units I think. How do you check your riser?
