    I am posting this for those people who find themselves wasting a lot of time trying to find a good fitting lower radiator hose for their LS swap. I read every post and bought a few of the recommended part numbers to no avail. I realized that not every LS swap is the same. Key differences are the thermostat housing (early or later years) and radiator selection (26" or 31" wide). My car has an Edelbrock pump and 31" Griffin LS swap radiator (1.5" id hose). I spent about an hour or so looking through the online Dayco catalog and found #71391. The picture looked promising so I bought it today and it fits like a glove after trimming about an inch off each end. Hopefully this helps someone with their swap.

    That does look good. What do you think of the radiator? I'm going to be in the market for a radiator to cool my LS7 once I start putting everything back together.

    I chose the Griffin radiator for a few reasons. I have been running one is my big block Chevelle and it cools a lot better than the 4 row copper/brass radiator. I liked the fact that it is a dual pass radiator with the steam fitting included. Also, it has 1.25" and 1.5" hose attachments which match my water pump. I figured that would make finding hoses a bit easier. Finally, this was about $250 vs $500 and up for everything else.

    I've been looking at the same brand rad. to put in my car. Will you post up the part number of the rad you used?

    I purchased 8-00010-LS. This does not contain a transmission cooler. There is a different part number if you need that.

    I'm running an auto, but I'm still not sure if I want to run a rad with a built in trans cooler or run a stand alone unit.

    Very sweet setup. I'll keep that hose number in mind. I'm going to attempt to use an '02 fbody radiator and fans.

    What part number are you running for a top hose?

    I believe it is Dayco 71951. I had to trim both ends to fit properly.
