Could it have been before the advent of modern ignition systems?

RE: street engine. I would agree, a street engine must work at a wide range of rpms and this is why I think mechanical and vacuum advance distributors were created.
RE: power through range. Again I agree. I was just trying to make a point that some of the advice on page one of this post might of been a little on a wild goose chase. If peak HP was what people were after on that dyno run, then muking about with various spring combos has no effect on peak...yet it would have effect on overall band and especially the lower band where street cars are driven.
RE: date of power secrets. copyright was 1983 and 1989. The book is getting a little old in the tooth but they do show a modern MSD box and distributor in the pages so it seems current with this technology.
