My radiator/fan setup is through Custom Works (motor is LS376) and one of the caveats is the upper hose needs to be spliced (98-2002 Camaro hose). Could I just use a flex hose instead? I am not completely averse to splicing a pre-formed hose, but think a one-piece hose would look nicer. There are tons of flexible hoses available, but are there any issues with using them? Any other ideas I should consider? Here's a shot showing the water pump I have, just for reference.
