I need a lower hose for a 1971 LS5 454 non AC 4 speed car, unsure of the cooling system rating. Can some one give me a part number or recommend a supplier? I have tried Gates and one of the online Corvette suppliers and have not found a hose that fits correctly. Old hose has
D 09112 and 76EP75 EB on it. TIA John
That does seem unusual that the hose won’t fit. It would make sense that the lower outlet on the radiator would be located in the same area as on the OEM radiator, but maybe not. What company makes the radiator that you have? I’d be interested to see if anyone else has had a similar problem.

I do not know the manufacturer of the radiator. It is for an automatic transmission. The problem is the lower outlet curves sharp towards the center of the radiator more so than any other photos I can find. There is not much room for the hose to begin with, adding to the problem. I am thinking the AC three pieces will give me some wiggle room. the 1968 427 hose looks more correct, but from what I can tell the 68 core is 22.5 inches and my core is 27.5.

That was going to be my question to the OP. Original Radiator???
I ended up going with a Dewitts in both a small block and a big block car because of the rad hose lower hose.
One of mine was a Champion - don't know the manufacture of the other one.
A work around?
Took a couple hoses I had laying around- cut them - duct taped them together at the correct angle. Then took my cobbled together hose with me to NAPA. The guy at NAPA lets me walk around and find a hose that will work.
I've done this several times with other cars and engine swaps.
Another way? Some SS exhaust pipe to attach two different sections.
Another trick is to use brass drain waste plumbing pipe ......much easier to get than stainless exhaust pipe, comes in bends too, or maybe a section of plumbing drain trap.....
