old school tunnel ram and carbs question

[musclcar]

i'm about ready to put my edelbrock TR1-X tunnel ram on my sbc and need a few questions answered.was there or is there a spacer or adapter to mount the carbs sideways instead of inline.the carbs i'm going to run are 1850 holley's now i'm trying to get a period correct look is this the correct carb used back in the 70's.on these 1850's i was told i need to run a balance tube for the secondary diaphram so to open correctly.was this how they were set-up back then or did they just run independent of each other. now the fuel line routing i'm currently running the stock 69-70 Z28 metal fuel line for holley carbs.this had a 1/2 line from pump to a brass fuel block then (2) 5/16th lines one to each bowl.i was thinking of running rubber hose from that fuel block to each carb does that sound period correct or is there another way.
