upper radiator hose
What is the best upper radiator hose used in the ls swap. I am using the stock 3rd gen radiator. I remember reading about it in someones post but cant find it now. I did find in some posts that a majority of people are using the Dayco 71321 as the lower hose without too many fitment problems. Thanks

V6 4th gen here, but can't remember which style (93-97 or 98-02)

According to Dayco's website that's from an LS1 Corvette, Camaro, or Firebird.
I'm going to get a Dayco D71321 hose and cut it down to fit.
