350 rebuild
Better upgrade to an aftermarket block first. Plan on spending around 2k for a block alone.
Edit - This is HUGE pet peeve of mine. This "NOS" you're referring to, is this nitrous "kit" made by Nitrous Oxide Systems? If it's not, it's not "NOS". It's a nitrous oxide. If it's an Edelbrock system, it's an Edelbrock nitrous "kit", etc.
