A while back I accidentally ran my Nova drag car at about 45 degrees of timing, locked out, from idle on up. It had race gas in it, and I was just cruising, so it didn't detonate, but a swear it got about 20mpg rather than the normal 8mpg. Don't know for sure, cause I don't have a gauge, just a fuel cell. Engine is a 355cid 12.5:1 compression small block chevy. Anybody else try running stupid amounts of off idle timing with any success?
