First Dyno

I am running a stroked 360 magnum 406ci, edelbrock heads, m1 single plane, 9-1 comp forged JE pistons, scat forged crank and h-beam rods, studded with cometic gaskets. Turbo action prepped full manual auto and 3.55 gears. I am fixing the slipping belt problem and will re-dyno next week and hope to get pics. Tony said I should easily hit 575-600 rear wheel horsepower maybe more.
