Hi Vince, here are some thoughts and opinions, take them with a bag of salt
CAMS
You've picked a pretty nice Comp cam. I like that it has asymmetrical lobes and is of the more modern designs. Here are three cranes that are rated for 10:5:1 10.5:1 and 11:1 that seem to do better than the 35-324-8
Comp 35-324-8

Comp 35-324-8 519@6000
Crane 448601 554@6000
Crane 448031 554@6000
Crane 448511 556@6000
that's 35HP, just by picking a different cam
STROKERS
I know everyone loves a stroker. If I was building an engine from scratch, I would go 351 or 351 030 over which is a 357 or 358. You can then use all stock, easy to find components. What does stroke really do? Stroke changes engine size. You get more torque from a stroker, not because of the stroke length, but only because you are making the engine cubic inch deplacement bigger. HP is directly correlated to RPM, where TQ is correlated to cubic inches.
What this means is that you can make as much HP with a 351 as you can with a 427 stroker, AND save a pile of money, AND avoid the dangers of higher cylinder wall sideloads and high piston speeds.
Anyone believe me? Here is a 351, this is the exact same engine from Vince1 above. Notice HP is the same, only moved right 500rpm

If you can melt the tires off any cobra at 300TQ, what is the purpose of 500TQ? Melt tires faster? One of the fastest street cobras that I have read about is Quik1 on the FFR boards. He runs a 289 with tons of HP. Hooks up everytime. Runs low to mid 10s.
If you own 40,000 acres of corn and a drive a big green tractor, then the pursuit of torque is a good one

If you own a 2500lb convertible that melts tires in all 4 gears, you might consider the pursuit of HP.
I think we often over value stroker kits.

You might check you AFR205 numbers. I believe the data on the AFR site is @ 28H20 rather than 25 and I think the the exhaust valve is 1.6" rather than 1.4

One other setting you might try are the sidepipes. I have found the setting that will bring you in closest to magazine engine dyno nymbers is small tube header to open exhaust. You choice is also a good one since the mufflers keep the data to the conservative side.
hope this info is interesting

I think you have picked some excellent components on your engine.
