Thank you for the article. I read it. While it addresses air fuel ratio and spark timing, it stops short of explaining what camshaft timing needs to be used to complement the max 10.5:1 static compression ratio. Could a guy supposedly use any cam he feels like using? That's what the article suggests. In other words, you could use a cam that closes the intake valve at 20 degrees and have the same results as another cam that closes the intake valve at 60 degrees. I call BS. If that's your "real world", I call double BS with sprinkles.
