Fuel sending unit question

Hi guys, I was wondering whether it was necessary to install a 3/8" fuel sending unit and toss the 5/16", or if the 5/16" is adequate enough for my car. I'm installing a mild performance 360 with an M1 dual plane and Holley 3310 and mild Lunati voodoo cam. Thanks for any help yall !!!

IMHO, with your combo the 5/16" is more than adequate
