Just had HPP in dallas tx tune my new setup. On 10lbs it made 615/566 thru a t56. I have to work out an issue with my ram twin disk, but I look forward to turning the boost up. New combo is F cam, FMS r block @ 4.125" bore, scat billet 3.1" stroke crank (made a short stroke 331), carrillo rods with JE 8.5:1 pistons and ported twisted wedge heads. On3 kit that I ceramic coated with a garrett 76mm turbo that comes with the HP performance kit.. Fuel system consist of dual inline walbros. Once I get my clutch fixed I am going back for more boost and tuning it on e85 with 80lb injectors but I think I will need more fuel pump.
