I recently ran my 11.5:1 compression 433 cube FE EMC combination at 29 degrees to eliminate detonation running pretty marginal 91 octane spec fuel. It made "only" 640 some horsepower that way - in competition. On the 93 octane premium from the corner Exxon station I could run with 37 degrees and it made 674 horsepower.

The short answer is thus "yes". It can be done because I and many others have done it with numerous media guys and witnesses standing around watching and listening. "Cheap" and "easy" are not terms I would apply to this engine though.....
