Mark D Posted August 3, 2021 Report Posted August 3, 2021 Here’s a guess, maybe somebody tried to put an exhaust whistle under the hood? When they sold the car they removed the whistle and installed the cap. 3 Quote
knuckleharley Posted August 3, 2021 Report Posted August 3, 2021 I think Mark D is probably right. I have never personally seen one of those things,but I remember that "a exhaust-operated Wolf's Whistle" seemed to be popular in the JC Whitney catalogue when I was a kid. In all these years,I have never actually seen one that was installed,though. 1 Quote
ChrisMinelli Posted August 3, 2021 Report Posted August 3, 2021 Man that is a deep dive if that’s what it is. Does a wolf whistle keep deer (supposedly) out of your way? I remember my grandpa used to swear by the air powered version of those. Quote
72morph Posted August 3, 2021 Author Report Posted August 3, 2021 Maybe to get Little Red Riding Hood's attention ? Quote
Eneto-55 Posted August 3, 2021 Report Posted August 3, 2021 I have no idea, and have never seen anything like that on an exhaust manifold, but is it possible that police cars had sirens that ran off of the exhaust? Quote

RobertKB Posted August 3, 2021 Report Posted August 3, 2021 I have a pretty good idea what it is. It’s either a thingamajig or a doomahicky. Outside chance of a doodad. ? Someone on the forum always has the answer. ? Quote
Plymouthy Adams Posted August 3, 2021 Report Posted August 3, 2021 I would think a photo from the side and below to go with the one show top only would be beneficial..... Quote

Loren Posted August 4, 2021 Report Posted August 4, 2021 In the 1970s I had a 49 Special Deluxe Two door as a second car. Loved that car! Anyway my Dad who drove it a lot put one of those wolf whistles on it and found it made dogs crazy! He would terrorize folks at stop lights who had dogs in the car. They would jump from the front seat to the back and cause all sorts of hate and discontent. My Dad had a unique sense of humor. I limited myself to the growl the transmission made when you worked the clutch. Apparently there was a bearing that was bad. It was loud enough it got the attention of other drivers (and Dogs) even with the windows up. The ears would go up but no hysterics. Quote
Dodgeb4ya Posted August 4, 2021 Report Posted August 4, 2021 I also had a wolf whistle. Went on the intake. Sure affected the engine smoothness. The Cow horn I also had was a lot more fun. Especially with a herd of cattle coming at ya! Quote
chrysler1941 Posted August 4, 2021 Report Posted August 4, 2021 The thang looks like heater disburse (is that a correct word?) Maybe added a tube connected to interior fan like VW to draw in heated air. Quote
DonaldSmith Posted August 4, 2021 Report Posted August 4, 2021 (edited) Lessee, a wildass guess- It's on the exhaust manifold, so we don't want it to release exhaust into the engine compartment. So maybe it lets air into the exhaust system? There may be a valve under that dome. maybe the finned shaft is to disburse the exhaust manifold heat, to avoid overheating the valve mechanism. To quote my 2-1/2-year-old neighbor boy, "Why?" Why introduce air into the exhaust stream? Even out the pulses? Edit: Boost your gas mileage? Extend you r oil change interval?

I understand once you get one of them tuned right,they are good for an extra 100 hp! They had to quit making and installing them in the 50's because they were breaking axles on takeoff and gear shifts. Quote
Eneto-55 Posted September 8, 2021 Report Posted September 8, 2021 How much pressure would you get on the exhaust like that, if, say, it was a connection for an air hose, to air up tires? Would it be enough? (I assume that others here have seen the air hose you could connect (temporarily) in place of one spark plug. That's what made me think of this now. I hadn't looked back at this thread since before the side view photos were posted, and those fins look like they're designed to reduce heat.) Quote
Plymouthy Adams Posted September 8, 2021 Report Posted September 8, 2021 unless you could plug the exhaust pipe...this larger opening would not allow any significant pressure...the spark plug access will allow you to build pressure on compression. Quote

Back when I was a kid and my family were beach fishing with nets,we used to have a device we could screw into the head of our truck in place of a spark plug,and then then start the truck and pump up the tires after coming off the beach. Had a long rubber hose with connectins on both ends that would screw into the device in the head and the tube. Quote
busycoupe Posted September 8, 2021 Report Posted September 8, 2021 I always wondered if those connections to where a plug was removed would fill your tire with gasolene vapor. Would the rubber in the tire be damaged? Would it be an explosion hazard? Quote
Sniper Posted September 8, 2021 Report Posted September 8, 2021 I already got one of those, it's called a compression tester hose. One end screws into the spark plug hole, the other end will allow you to hook up an air hose. Schrader valve in the adapter hose makes the air flow one way. Quote

I have a kit called "Enginair" My daughter, who has a knack for finding stuff, gave me this as a gift several years ago. ? Quote

IIRC,the one we had came from Western Auto,and was in a tin container identical to the one you used to buy propane torches and bottles in. Ours also had a solid rubber hose. I THINK it came from Western Auto. Anybody else remember Western Auto? Quote
