71 heater hose question.
Sorry dum dum moment!

AC cars used heater hoses with molded ends. I'm guessing that since they didn't have hose with molded ends, they used longer hose so that they could put a big loops in it, to avoid having it kink.
I can't say why there is a overflow tank on it.
I'd be a little concerned about the plug in the valve cover, where the breather or PCV should be. I'm wondering how they're venting the engine?

Not a deal breaker ....but...I just repaired a Corvette this past week that had a totally screwed up PCV system....and this car seems to be the same but much easier to get correct than what worked on.
In the photo below...the plug that looks white that is in the valve cover ( which is valve cover for a Tuned Port engine) is plugged or capped off.
IF there is a PCV in the other valve cover (left valve cover)...than the white plug in the valve cover needs to be taken out and some type of filter installed.
Due to this valve cover being capped off....the engines PCV system is being suffocated. Becasue where is the filtered fresh air coming into the crankcase area at in order for the PCv system to do what it is supposed to do??
For those who may not know...the PCV system is designed to draw out the combustion gasses that pass by the rings...and build up in the crankcase area....and the PCV pulls these gasses into the carb so they can be burned.
And keep in mind....if you pull out this plug and the left valve cover has the PCV in it and it is connected....and you place a dollar bill across the grommet in the right valve cover while the engine is running and it does not get sucked to it....that is telling me that either there are leaks in many of the gaskets...or the engine has more blow-by than the PCV can keep up with. IF the dollar bill blows away from teh grommet or you place your hand over it and feel puffs of air blowing against your hand...then the engine is SHOT...more than likely. Excessive ring wear.
