I second that.

You can either go with the Walbro 255lph or you can go with the Walbro 255lph HP, which is for "higher" horsepower cars. Check it out.

Both...you'll be fine.

I would also get an upgraded fuel rail w/ a FPR...and if you really want to get technical, you could also run SS braided fuel lines

Walbro 255 hp, fpr, 1000ccs are enough for 600whp safely.

just to clarify the HP stands for high pressure and is pretty much exactly the same the the regular except that it can still flow a decent amount of fuel at 100psi and up. they both flow almost exactly the same until 60-65psi. after that the regular starts to drop off rahter quickly.

but ill agree with everyone else and say that the walbro will be fine at 500whp.

Right..I understand this.

I was just clarifying to the OP that they had two different versions of the Walbro out. Thanks for going into further detail though
