Default Back to Basics for HP

Hey all,
I have a couple of ideas to throw out there for the 700 KFX.
The manual says to set the timing at 28 degrees for 5000 rpm.
Almost every engine I've ever worked on took like 32 degrees of total timing OR MORE depending on the fuel used.
Since Timing makes HP, have any of you ever increased their factory timing and run colder plugs?

I'm sure the factory put that total timing number on the manual because some people insist on running junk gas. But what if they only ran 93? Or what if they only ran Race Gas?

Think about it........

I don't doubt you can make a couple more hp by advancing the timing on a V Force or P 700, but......in general more timing does not mean more hp...it means you are fighting a less-than-ideal combustion cycle. Example: I had a SBC 406 that loved 36* BTDC. I changed the cam: guess what? The EGT dropped 100 degrees, it made MORE hp, and it wouldn't pull a sick (ahem!) out of bed above 34*.

Hope this helps.
