Finally made to the dyno a couple of weeks ago. Not bad..found out that things are working properly, AF ratio was 11.8-12.0 range and steady as a rock. Boost retard was working properly and the new cometic head gaskets held up fine. 455 hp at flywheel, 359 rwhp, 398 torque. All at 5900 rpms. Blower only made a bit over 10 lbs instead of the 12 it is suppose to make, needs to be re-ribbed. Using the boost retard switch, taking out only 1* of timing vs 2* made a 36 HP difference. She wants more timing and needs more race fuel. Alll in all pretty good. Happy that the boost retard is working properly and AF ratio is almost perfect.
