When I rebuilt my 2.7 with RS P&C, 901 cams, Webers and SSIs, I also had the distributor re-curved (by Stoddard). Below is a graph showing the old (CIS) vs. new advance numbers.

Btw, I am reading this thread with interest because I am contemplating moving to a twin-plug with 10.5:1 JE Pistons, but Grady's comments on the longevity of JE pistons are causing me to pause. What is the highest CR I can safely run on 93 octane (US) fuel? Would 9.5:1 be a better choice? Note that I would also be installing an electronic ignition system (Electromotive XDi2) for the twin plug setup (this will also allow me to optimize the advance curve on a dyno), along with a knock sensor. And what HP can be expected from a 2.7 with this setup?
