Stock fuel lines for 1000HP? 01 Silverado that has a LQ4 with LS3 heads. This is a turbo set up and have dual walbro 450's in tank.
Will the stock 3/8 (feed) and 5/16 (return) be enough for 1000hp?
Since LS3 intake is returnless I have to add a AN fitting to the stock passenger side rail to put my fuel regulator on return side of fuel and curious if any one knows a good way to go about this.

Pump gas or E85? You'll probably need to make the jump to at least -8 for pump gas. -8 or -10 for E85.
It's probably not worth the risk of fuel starvation (or overheating and burning up your fuel pumps). I've also heard the returnless is only good for ~700hp, though I'm not sure of the validity of that statement.
