proper fuel system upgrades I just had my lt1 rebuilt as a 383 with forged crank & rods and custom je pistons, with lowered rings for n2o. I "should" have at least 400 fly wheel hp with my new heads and cam. I want to upgrade to a direct port nitrous set up. I will be jetted for a 200-300 shot. I have a stock fuel system other than a walbro fuel pump and an aeromotive fp regulator. what upgrades would be needed for these fuel demands?

I would use the Walbro pump a STOCK regulator and a dedicated low pressure fuel system for the nitrous shot. By low pressure I mean used a carburated fuel pump and regulator and carb pressure sized fuel jets.
With that size hit they are going to have momentary lean problems with a single in tank pump.
I hope you are way off on your flywheel HP estimation, I don't think I could figure out how to build a stroker that weak.
