I mapped an over 300 degree cam engine last week that wanted to be low 13s in places where I would normally have prefered high 14s, but the difference in now it drove dictated what it ended up with.
And bear in mind you wont find peak ignition via det, you need a set of rollers.
cheers, i had a feeling it was going to have to be rich to make it run sweet (its not my fuel) also ill be using the arse dyno initially but a RR session will be on the cards eventually, what sort of timing figures will i be looking at at what rpms very roughly?
