Need a cam recommendation

[Blackhawkdc]

I'm building a 496 stroker for my '69 1/2 ton. I'm sure some of you have seem my posts with other questions on this engine. But I'm looking for camshaft recommendations. I'd like to get 575 horse and 575 lb-ft of torque out of her. I'd prefer to stay hydraulic-flat tappet, but am willing to go to a solid lifter design. I'd love to convert to roller, but can't afford it. The engine will be about 10.2:1 compression, backed by a TH400 w/full manual valvebody, 12-bolt rear stuffed with either 3.73's or 3.55's, haven't decided yet. Any ideas out there?

Thanks.
