Explain Quench to me.....GO!

My 367 runs .034Q/10.7Scr, with KB167s and Eddies. It seems to make full power on 32*,and is quite happy on 87E10.With a 223/230/110 cam, it made phenomenal fuel mileage. It hasn't been opened since 2004, and has over 100,000 miles on it.
Is it due to the Quench?
I like to think it pays a significant role.
