I have checked the manual with this question, and done some searches, but have not found any information on how to determine size of fuel rails required.
462ci V8 naturally aspirated. i expect BSFC should be below 0.50 and power will be about 525hp. injectors will be 42#.
I have not decided on 3/8 or 1/2 fuel line (taking suggestions), but right now I am building the top end on the motor. Ross sells 3 fuel rail extrusions; either 0.500" ID, 0.690" ID, or 0.800" ID.
Does anyone have any tables or information on how to properly size fuel rails?
Thanks in advance,
Scott.

I was going to leave it to the machinist to thread the end of the rail.
