The power valve is not needed unless you drive it, for a race car, ditch it. For a street car, keep it.

For some quick free advice. Send an email to 3-4 of the carb guys & fill in their ?? sheet.
With that info, you can judge which is the best combination for you toy.
You might need a 700, you might need a 850?? They are usually pretty accurate of the combination needed,
with the proper information in hand.

Good luck.

The 30cc acc pumps should work very well, the HP main body is great, the proform unit might save some money and is just as good.

NP, i use 570s for my 383 and they work very well, i built my own DP 750 with the pro form main body and the quick fuel base plate, thing is sick, doesn't like low revs with a manual trans, but what big cammed car with no gears does.
