EFI basic math

[Mr.WFO]

if i were to build an intake for my truck to run MPI, 8 injectors, how would i figure the size/flow rate?

if i were to start with the 351c-400m intake adapters, build runners off that how would i figure throttle body size?

does runner length affect powerband regardless of where throttle plates are?

is there a website with a calculator for this kind of stuff?

i'm just interested in the math, this engine wouldn't be worth it, but perhaps a 300 inliner would...especially if i wanted to run a blower...

i know there have been books written on the subject, anyone know which one i should read first?
