Like the title says. I put an LS 1 in my 70. What are you guys doing for hoses
Did you find an aplacation or just trial and error ???
Thanks

Top hose on my 87 is stock 2001 Silverado and I am almost positive the bottom is too. Jay

I use the stock Silverado upper hose too, on a stock '72 radiator it takes a bit of work to get it the radiator side on, but it will go on, a little lube helps. On the bottom I use a Gates #20931. You can see a pic in my build thread, post #88
