The fuel is close enough to get you started but you might want to bump up the low rpm high load timing map a good bit. I had to lower it as far as it is due to the shaved head making it knock real easy. So if you are thinking about it don't bother, shaving the head sucks on the G10 engine.
Get a standard GM knock sensor and hook it up to a tape player adapter or fm modulator so you can hear it through your stereo and you can set the ignition timing pretty good without needing a dyno. Just clamp the sensor into the engine mount or somewhere else solid on the engine with a pair of vise grips. Of course a dyno would make quick work of tuning the engine properly so it would probably be worth visiting one if there is one close by.
