I am running a similar set up and going with 3.55s Why? Because that is what I have. Might have to drop down at some point.

Twin turbo c5

Ive always had goodluck with 273 to 355. if your a daily driver. if your just drag racing maybe 373 or 410. I've went from 273 to 373 and to be honest no difference in the et . And it sucked to drive with 373.

You will have issues loading the motor to build boost with 4.10s. I have 3.55s and they work pretty well with a 4L80E.

Use the 3.27 and that single disk Yank won't hold lockup too long before it burns the clutch at WOT. Done it twice.

Why a 80 if its a weekend warrior or track car? I have 3.08 in my rear and it spools the turbo nicely.
