I have found that, Usually, lower compression engines make more power on a little richer mixture.
They can also like a degree or two more timing than the same combo with hi compression

I am far from scientific in any of my tuning, no afr meter, no egt, just tuning on my 10.5-1 alum. headed big block. I run my timing locked at 40* and the 1000hp is jetted 87/92 w/ rear pv blocked. It falls right in line with the fat/advance statement made above
