To Much Timing on Low Compression Engine?

I know you asked about power; but don't forget there is just so much you can do with the stock dizzy, before you have problems at the other end. For instance it's rare to find a dizzy with more than about 25* in it. so to run 50* of power-timing would require an initial of 25*. This may work at idle or very lightly loaded. But the rate of advance might be close to 1 Degree per 100 rpm. So with an 1800 stall TC, the timing might already be 35*by then. I've never had an engine that liked that, and 25* may upset the starter. 'Course I've never had an engine that liked more than 36* power-timing.
So I'm kindof curious what you're thinking is.
