osd9: very nice numbers indeed. After flirting through the hundred or so performance specs of a 01Z, I can't recall a 390. So you must have had a decent tech set a few things to the high side of spec.
A few things I noticed was a 16:1 compression ratio and 15*static timing up to 375 horse... 15:1 and 12* timing there on up.
tobnpr: I read the service bulletin and it calls for some fuel pump bonnets, sea water pump work, heat exchanger, ... looked expensive. The real power comes from bumping up the fuel setting and raising the high idle rpm! It's been my experience that a Cat always could handle a little more in it's stock form. I still do not know what your stock settings are! But a 435 has a high idle setting of 3186. If you did nothing more than set your high idle to that upper range, opened up your fuel screw as little as 1/4 turn, you could see gains close to osd9's. Advancing the timing to the high site of spec which is 17* static helps big time, but head gasket failure seems to follow later down the road. So I would stay away from that if it becomes recommended by your tech.
