You guys may be getting tired of my endless questions, if you are I am sorry. I am overseas with a lot of time on my hands. That means I spend a lot of time trying to learn more about engines and off road trucks. My heart is in the engine though I will tell you.
Now to my question, I am currently running 1/2 fuel line on a carbed Blown BBC 427. When I convert to alcohol and EFI, I know that the fuel line size will have to change for both reasons. The EFI side I think I understand, my question is how big will I need to go with the fuel lines. I am sure there are a lot of variables that I may miss. So the stuff I do know
Engine specs of what I have. I don't know what cam is in it right now, my cam card is at home, and the wife ain't gonna look for it either. But here is what I have on the engine. It is a PAW Kit engine.
BLOCK - 4-bolt main 427 seasoned block bored oversize. Block is hot tanked, custom honed, dry decked, line honed, new cam bearings installed. Engine block is painted inside Rustoleum to aid in a quicker oil return. Brass freeze plugs installed. The Outside of the block is painted with your choice of factory colors.
CYLINDER HEADS - New RHS™ Pro Action cast iron rectangular port cylinder heads castings feature 320cc intake runners. Stainless 2.250 & 1.88 valves. New perf valve springs which will handle up to a .600 lift cam. (Larger cams or solid lifter cams will require optional valve springs at extra cost.)

RINGS - Premium Speed-Pro moly rings.
RODS - P.A.W. 6.135" high performance connecting rods which have been shop-peened, checked for straightness. Resized on the big end and fitted with high performance 3/8" chrome moly rod bolts for maximum strength and performance.

Headers on the engine are 1 7/8 primaries, (I am sure a lot of you are going to say are WAY TOO SMALL, but that was what would fit between the frame rails at the time the engine went in. 2 1/4 Collectors to dual Super 44 mufflers. I have electric cut out installed.

Rockers are stud girdled

This truck is used as a mud truck and trail truck with some street use.
If you have any advice, or just want to laugh at me I am good with that.
I am looking for knowledge here to help make my engine better, so your advice in any area of my truck is greatly appreciated. I am not proud I just want to learn. Let me know what you think
This picture is before the up and coming mods. It is carbed right now. Again let me know what you think. GOOD OR BAD. Any advice is appreciated. Thanks in advance.
