Cam Selection Advice

Hello everyone, yet another cam selection advice thread!

I need some help with cam selection, as I'm not well versed in cam selection and I'm a little off the beaten path with this one. I'm open to anything out of the catalogs or custom grinds, basically any advice you'll feel like bestowing on me. The car is a '69 Valiant with a 360 Magnum hyd rollers, IMM 2.055 Speedmasters with Comp 914-16 springs, and 1.5:1 mancini rockers. Two choices of intake, airgap clone or super victor, both set up for port injection. Ram short tube headers into an ebay gt45 turbo. FTI 4000rpm stall converter, 3.73 gears, and 28" tires. I have enough fuel system for 700 crank hp, but I don't think the stock bottom end will hold up to that, so we'll save that for the forged rotating assembly.

Any other info I can give to help please let me know. Thanks!
