Those with Griffin 25241-X...radiator hoses? I started finishing my build for the year and found out that the stock radiator hoses wouldnt really work for my setup. I was looking at those Goodyear/Dayco flex hoses on Summit, has anyone used these? If so, do you have part numbers or all the inlet/outlet sizes? Im having issues finding them.

Ok so it looks like the waterpump inlet should have a 1 1/4" hose end, and the radiator inlet is 1 1/2", while the radiator outlet is 1 3/4." Does anyone know the size that would work for the thermostat? NAPA says the OD is 1.65, should I do a 1 1/2 or 1 3/4?

I'm going through the same thing with a 55241, but they both have the same outlet/inlet config. What I found was that the pump inlet/thermostat is 1.5 and outlet is 1.3125. I was planning on either using the summit universal kit with the flexible stainless hose, and adapter ends, or go with a dayco flexible hose. I had 2 part numbers 1 for inlet and one for outlet... 81081 and 81091. I figured a 1.25 hose would work over the 1.3125 outlet.
I hate to see rubber hoses ruin a clean engine bay.

I used the stock hose on top & a rubber flex hose on bottom from a parts store. I dont remember size though. Its got kind of a kink in the bottom because of the angle of the rad. outlet but doesnt overheat.

I like the flex hoses but my issues is that the longest one they carry from waterpump(1 1/4) to the upper radiator(1 1/2) is only 19.5" and all my measurements say I need about a 22".

I found 2 parts at Napa that I plan using because the dayco reducing hose didn't look long enough;
FF266 a 1.5x22 flexible hose
NBH900 1.5 to 1.25 radiator hose reducer bushing
