Default 02' Z06 fuel system limits?

After taking out #7 in the stock shortblock on my heads/cam Z 3 months after buying it I am looking at preventing any more problems in the future. Trying to make sure I have enough fuel 450-500whp 347 or 402. I plan on running 30lbsvo injectors, but do I need anything along the lines of upgraded fuel pumps or wiring?

I might run a wet nitrous steup in the future so I won't need anymore injector, but will the stock fuel pump supply enough fuel feeding the 30lb injectors and supplying the fuel for the 100-150 shot?

The stock pump is barely good to 450rwhp. You will need to upgrade the fuel pump. A replacment Walbro pump will be good to about 600rwhp.

450whp is all. I was under the impression that was true with the f body guys, but most vette owners claim otherwise. Damn I never get consistant advise.

I've always heard ~400 for both F and vette cars.

So just a simle walbro drop in pump is enough for 600whp or is that rewired, etc? Are there better alternatives to the walbro's? I've seen a lot of people with bad walbro pumps in my time.

Keep in mind this is on my 02' ZO6 with the furl return located on the fuel filter.

If spending all the money on upgrading the motor why not go with some cheap insurance compared to the cost of a rebuild.
