Thank you for the questions, goal is to be around 600hp to the rear. first dyno pulls are at 524hp and 550 tq at the rear @5300rpm with the current 255 fuel pump. Starving for fuel so I am having bigger rails made with 8an fittings to the pump. Would like to know if anyone has used this particular Walbro 400 fuel pump. I was considering using the 340 stealth, but it would be running at the max.

I'd like to hear more about this build. Just me throwing spaghetti at the wall but have you considered duel Walboros? I guess depending on how much the 400 cost. What kind of build you got?
Yes, was considering two pumps however it looks like the tank will be modified to put in a A1000 efi pump (aeromotive)(over kill,yes) AN8 lines, regulator and bigger rails. Gil Navarez is my tuner @ Shelby American in Vegas. The ingredients are as follows...

Still would like to know if anyone has had a 400 Walbro pump put in their 90/91 vette though.
