A couple questions about supercharging a 440

Hey guys, I'm planning to supercharge the 440 in my '67 barracuda, and I've got a couple questions before i go ahead and start ordering parts. First off, how much could the stock crank handle with a 6-71 or 8-71 blower? I'm assuming it's cast because i don't know the serial number on the block, but i know the bottom end is Indeed fresh with about 500 miles on the new bearings. I will be installing a set of forged rods and pistons so I'm not worried about that, I'm just hoping i may not have to pull the engine to swap the crank. I'm shooting for 600hp, and I'm sure that's easily achievable with a blower and a proper tune job. Would a stock cast crank be up to the task if the rods and pistons are forged?

Also, i am going to install a hydraulic roller cam, the specs are 243/251 @0.050" and 0.560"/0.565" lift with 110 lsa. Would this cam work alright with the blower? Or would it have too much overlap? If it will at least support 600hp I'll be fine with it, I'd prefer to have a choppy idle if at all possible. Thanks for any advice in advance, I've never built a forced induction engine before but I'm looking forward to it!
