I mean Compressor for air condition

Yes I get that, but how is an AC compressor interfering with the lower hose on a regular small block when the compressor is mounted off the head and top water pump stud. Can you give us a picture

Okay, I didn't get it had the serp belt set-up. I had a serp belt on my 400 small block in my flat bed, but the setup I had was identical to the one on my suburban and had no issue using the factory hose. So that being said I don't know what to tell you there other than you may have to change the bracket kit

Maybe call their tech support and see if they recommend a certain part #. I would imagine one form a 92-98 truck hose would be the one to go with.

I know this is old but Did you ever figure out what hoses you needed? I'am putting the same bp set up in my 68 stepper right know.

When my son built his 70 he had the serpentine system and we ended up with a 95-97 don't really remember the exact year like in Grumpy's post #6

On those serpentine systems they changed the angle of the dangle on the water pump suction, if I remember correctly we had to trim a little bit and we then stuck the radiator end into a coffee can of hot water to soften the rubber to stretch/slip it over the the radiator nipple.

The local Oreillys lets me wander around their hose inventory in the back room. I bring along a wire pattern that helps get me close.
