Question compression ratios and method of compression

For those of you who are not afraid to rip apart the block for more power, higher compression can help. On this note, i have a few questions.

1. What compression ratio's are you guys using?

2. How did you achieve said ratio(i.e. "stroker" crankshaft, longer connecting rods, custom pistoms, shorter cylinders, etc)?

3. In the Automotive Encyclopedia i have, it says that General Motors did several experiments many years ago and decided that in gasoline engines, the optimal compression ratio was 17:1. Have any of you actually gone this extreme? if so, how and what are the results?


Thanks to all the people on here who have taught me so much, and will (hopefully) continue teaching me for years to come.
