I'm glad you qualified the fact that It couldn't be done without some kind of engine management system. Which is one of the points I've been trying to make.

Now I'm not exactly sure how Larry does it - but by reading his various articles and posts it takes 3 items working in concert to achieve the results he gets.
1) The Chamber being configured in a specific way
2) The piston dome shape
3) The camshaft design

He does say that some of the cams he uses are hard on the components, meaning that this type is not acceptable for normal street use. My difficulty in reasoning out the 87 Octane and Hi C/R is exactly where is the limit?

Could we condeivably design the piston dome to go up into the chamber and create the shape that he describes and just not even worry about the C/R?
Not without being able to test it on the dyno first, and at 500/day it gets very expensive. I'm talking non-computer, everything mechanical! I have a F.I. system that will deliver the correct A/F to whatever setting is chosen, and this can be either constant flow or sequential flow. The ign-timing will be more or less fixed but adjustable through vacuum and normal weights.

Now the 4th item that he only implies is the exhaust system and its ability to remove all the impurities. Bill Million of Headman developed the step-tube header and now they are also combining that with Merged-Collectors. But if you study the dynamics of the exhaust and make the connection to Jet-Engine theory you find that the exhauset has power stored within it that can be used to increase engine efficiency. Now when we can couple all of these together we can successfully reduce the exhaust cam duration and its Blow-Down affect on the power stroke. (Exhaust opens BBDC)

Consequently we can increase the intake cams capacity to fill the cylinder and not have to worry about the contamination created by longer duration, and higher acceleration ramps. The added benifit to all of this is that we can use the overlap (the Hidden 5-th cycle) to cool the top of the piston and chamber area thus reducing the tendency to detonate.
