Hot Rods What is this thing mounted on the highboy firewall?

Attached is a copy of a photo from the Rocco & Cheaters photo collection. The engine shows to be a 1956 Corvette 265 since it has certain features which were unique to that engine. The engine appears to be in a '32 highboy. The question is: what is that round thing mounted on the passenger side of the firewall?

 

Can’t open that

 

Looks like a vacuum cylinder like what would be used for a power brake booster.

 

Won't open here either.

 

??? Nothing

 

Vacuum brakes maybe?

 

Looks like a vacuum booster for brakes off a ford big truck like a f600

 

Looks like a brake booster made into a crankcase vacuum canister... think vacuum pump.

 

could be a HydroVac brake booster, mounted in a strange way? or it could be something else...

 

definitely looks like something that needs to be removed no matter what it does.

 

Blow-by/oil separator using recycled parts, and it looks to drain back into the oil pan. Wrong WCFB carbs for a dual quad set up; both have chokes and are connected to exhaust manifold heat via a "T". Maybe this engine should be installed in that South American 55/56 Wagon/Delivery? I am Butch/56sedandelivery.

 

Guaranteed the best Vacuum Wipers and Advance...Bar None with the New Improved Super Sucker...Amaze all your friends today...

Well at the very least it is function over form...No doubt about it...

 

That is a hydro vac brake booster from a truck. I don't know what purpose it would serve on that roadster. I would take it off

 

How about an accumulator.

 

I could be wrong but it looks like a flux capacitor to me.

 

Here is the photo enlarged a bit



And just the mystery

 

Looks like ugly.

 

Kinda looks like a heater hose coming to it.

 

Squirrel wins the Chicken Dinner again . HyrraVac unit from a larger truck or bus chassis . Only issue here is it looks about as bad as I have even seen and it only works with a single chamber MC .
