1LE and ZL1 have the same diff and axle shafts, I am not sure about the driveshaft. It is pretty easy to tell as the ZL1 shaft gets fat and the plain LT1 shaft is the same thickness. You can search on the powertrain thread where I bolt in a ZL1 manual shaft into my SS.
Not to confuse you I'm just saying I running ZL1 shafts on my SS setup and they can take some abuse but not IMO I'm building a 1/4 mile high HP car type of abuse. Should I call it "normal" abuse?
Yeah, you have to look at what DR fits on a 1LE wheel, I'm sure there are guys with it. Brakes unless you are doing road racing should be OK.
edit, I just checked and the 1LE runs the SS driveshaft so you need a real shaft, minimally that would be a ZL1 shaft, but since this a dream build, I'd get a carbon fiber or alluminum one piece shaft aftermarket and a driveshaft safety loop (required at some tracks for 10.99 and below in the 1/4 mile.

Here is what a ZL1 driveshaft looks like.
Once again for about 700 WHP and drag radials I think the ZL1 or 1LE axleshafts and differential are fine.
For 700 WHP the SS or 1LE driveshaft is hopeless and you need minimally a ZL1 shaft
For serious 1/4 mile IMO none of that stuff can take the abuse including the manual trans and that would require a complete 9" conversion and ZL1 manual transmission and an aftermarket clutch, might as well toss in aftermarket throw-out bearing, slave and slave line too. many strips require blowbell at this level of performance.
Here is the 1.5 SFI multiclutch specs:
