I would say for your application, the DW300 is up your alley. The Walboro is good for about 500HP which is what you're hoping to achieve, but rather then stressing your pump and pushing it to its full limit, why not spend a little bit more on the DW? Double-pumper is a very nice kit used by many high-horsepower cars, and if you can afford it, why not get it - but bang for the buck and meeting just your needs, I would say the DW300.

I only made 408 on GST's dyno with one Walbro 255 and DW 1000cc injectors. My injectors hit 98%. I think your injectors may be to small. Depends on the dyno. As far as pumps an aerimotive or DW pump would probably be sufficiant but I am not sure as I have not seen many buiilds using them yet. The 600 number used would be on pump, not E85.

Buschur Double Pump and ID1000, and you'll be good

I was refering to GST's dyno which reads much lower than most dyno's. We did not even come close to 500 with a similar set up. But it may have been the pump and not the injectors. And on another dyno I probably would have been a little higher.
