I have a 1980 Corvette and I’m just completing a frame off restoration.
I install a new Chevrolet crate engine and trans. It’s an LS3/525hp. I also purchased a new Dewitt LS style radiator for my vette.
Does anyone know what radiator hoses will fit? I figured maybe a new model corvette with an LS3, but it doesn’t.
Just thought someone might have run across this problem or at least hear me in the right direction, instead of making trips back and forth to the parts store. Thanks in advance.
To my knowledge there is no single piece hose that will work. I think it is a few trips back and forth to get sections that partially work. I pieced mine together from separate sections.
Have you solved all your clearance issues? Water pump and heater connections?
I also have an LS3 with with the Dewitt LS radiator. I looked through my paperwork that i kept and found a gates hose wrap wtih # 21953 for the lower hose and # 22625 for the upper hose. give these a try.
