Can someone please help me with sizing a trough. I have 16.572 of wire fill and i will be using 4- 8 hole gutter taps for 350.
 
Your connections may have more to do with sizing than your conductors. What is the maximum number of conductors you will be connecting at any one point and what method (Polaris, distribution blocks, split bolts) ??

8 conductors and Polaris.
 
check a catalog but an 8 port 350 NSI polaris is around 8" long. that will likely be the key factor on selecting your wireway
