Default 4.8l project

Hi guys, looking for input and opinions on my winter build. 1999 4.8l, stock bottom end, 243 heads from tbss (going to mill 0.035") gt2 cam, tbss intake, 8.1l injectors, shorty headers, no cats, dual exhaust. 2800 stall and switch to 3.73 gears.
Should I get a 90mm tb? Is the tbss intake a waste with the 4.8l?

Thanks.

Describe the vehicle it's in and your goals/intentions for it.

I've got a 4.8 & my opinion is get a 6.0. Doing all that stuff to a 4.8 is only going to hurt your feelings once you're through & realize that it's not that much more power.

You've got a good list of mods, just need to change to a 6.0 short block
