I have had no problems with the Carters in the past.
If you are going to turn any rpm over 6500 or so make sure you get a lightweight fuel pump pushrod also so that you don't have problems with pump arm float, ARP has a nice one.
You will be asking a lot of a mechanical pump if you use nitrous and keep the stock 3/8" line size. Smarter move would be to add a second line and an electric pump for the nitrous, it does not like pulsed flow, steady flow is much better. Carter makes a nice quiet electric that would work well for this, and you would only have it on when you are going to be using the nitrous.
