Clois,
I had much the same things in my 408 as you do and when they dynoed it I had 527HP at 5900 RPM and 526 pound torque at around 4300 if I remember correctly. I may be off a ways on the torque, but I am sure of the horse power. My 418 put out around 530 horse and over 500 pound torque but at a higher RPM as it really wasn't built for the normal street driving. Good luck and I hope that your numbers come out where you want them.
Ron
