5/16” may sound small but I got that direction from Gordon Stoney who was supervising engineer for Hydromatic Division at GM.
I autocross (not very good at it) and “spirited driving” on the street.
Mark Bowler sold me the transmission case fittings from Sonnix and he knew I was running 5/16” lines with no worries.
CONCERN: make sure you get the proper trans case fittings because, at least for my 4L80E, the rear fitting has a nozzle that lubricates rear spider gears. No nozzle = burnt gears! I learned this from Mark Bowler.
If you go flex, please get PTFE.
Thanks and best of luck
