Smile 68 GTO 400 Engine Build Feedback

I'm finally getting the correct engine into my 68 convert. Since i haven't been up on the latest, I'd like to hear your experiences. I want to keep it basically stock appearing, with correct date codes, but warm it up a bit. Car is original. Might be driven ~1000 miles/yr and might see a quick run at the strip, but not often. Thanks!
68 GTO convert, stock AT, 3:55 rear
400 SR block with #16 heads, regular valve job
Stock intake and probably stock Quadrajet (any tips on rebuild?)
~30 over, forged pistons, stock replacements, Stock rods. Compression will likely be close to 10:1 and I'm told that shouldn't be problem with the amount I'll drive it.
Debating between the RAIII or 068 cam.
Distributor (worth converting the stock body to electronic with kit from PY?)
Add HO/RA exhaust manifolds. OK to use stock exhaust or is it worth increasing the size?
RA oil pump?
Stock fuel pump? Fuel line? The 350 block in the car seemed to starve for fuel on hard accel, so wondered if the fuel system is worth improving.

Thanks for the info and hope this isn't too basic. It will be great having a real motor again!

Any other worthwhile upgrades? Any recommendations on the TH400 if I have it rebuilt?
