Radiator and swivel thermostat housing questions

[flipper58]

Was wondering if anyone has dealt with this issue. I currently have a SBC in my 71 and am looking to replace the radiator with an aluminum one with dual fans from a vendor on this site. The plan is to later this year swap in an LS motor. So, it makes sense to to me to get radiator that will fit the LS engine application with the upper radiator outlet on the passenger side. In the meantime, I plan on running with the SBC and have considered using a swivel thermostat housing to make my upper hose search a bit easier. Will that work? Has anyone ever done this and, if so, what did you do? Any other ideas?
Thanks,
Phil

I do not have the exact same setup as you but have and still use the below swivel neck on several of my motors (small block & big block) without issue.

I don't see why it wouldn't work, just need to find a hose to work with it. I would like to give you a heads up on the aluminum swivel housing with the o-ring. Mine leaked so I bought a brand new one which leaked as well. I bought a new o-ring, still leaked. So after reading lots of threads on the net about it I tried Permatex Black RTV AND the o-ring. I put the RTV on the housing, then put on the o-ring. I then covered the o-ring with a healthy amount of RTV (between 1/8 & 1/4 bead), finger tightened them, waited 2 hours before torquing them down. That was the only way (out of a half dozen different attempts) I could keep it from leaking. Been about 2 weeks now and not a drop. When researching the problem I found that some could get them to seal fine with just the o-ring but it seems the majority had leaking issues and had to add some type of sealant.

Then after you do the transplant just twist it to the right location and repeat the sealing process.

I hope that helps.

Thanks very much for the link on the swivel thermostat housing and rtv tip. Good stuff.
