fuel system opinions needed on e85
My lq9 shot a piston out the block and going to drop a stock 5.3L in for awhile the question is I have 60lb injectors on stock fuel rail with stock lines stock regulator with 255 fuel pump on 10lbs boost on 93 octane and like to keep my power level at 500-550hp were I was before with old engine. like to switch to e85 what will be needed to supply enough fuel for my setup with that power level? I have a small budget at the moment on this swap?

Thats not enough injector for 550rwhp. 60s@4bar will get you about 475rwhp regardless of the pump.
I would get some 80lb@4bar for your goals (lets call it 600rwhp). A single walbro450 might be ok at that level, but you would be much safer with a dual pump setup (like add a 450 to your current 255) or a larger a1000 or mp4303 single pump.
