Smokey Yunick's "100 mpg" was just hype to get sponsorship money (recent video by dragboss garage with Mike Campbell). Engines today burn over 98% of the fuel, so there's not much gain to be had (wrt combustion efficiency). "Cracking" or "catalyzing" fuel, heating, or any other processes, mathematically can't offer much gain; even if they worked. There's just no way to get around the fact that a vehicle needs a certain HP to move it down the road, which requires a certain amount of fuel to be burned.
I'm not expecting to see a huge increase of mpg with my car outside of a very specific set of conditions. I'm mainly curious to see what the "best" LS head can do, and how lean it can tolerate. With porting and some other mods I should be able to push it a little further.
