Radiator Hoses for 355 Gen I SBC & Aluminum Radiator with twin 80W Fans in my '67 C20 Restomod.
The expensive Mishimoto silicone hoses I order (via eBay) to have on-hand when ready to install DID NOT FIT.
So after some research, I used NAPA PN 7368 for Upper & 7463 for Lower (basically GATES Hoses I understand), that work with a later model 350 SBC in a K20. Had to also get a later model thermostat housing to direct the hose in right direction, but as pictures show, both upper & lower now work. & lower hose now clears the frame too!
Yes I have not put clamps on yet, but will do that & call it a night.
Listing this for reference.
