The Stovebolt Site Forums The Shop Area The Electrical Bay horn location.

I am trying to determine the type of horn and the location of it. Also, many horns are sold in pairs and I thought I need only a single horn. When I acquired my 1953 panel, the horn that came with it was quite long and fastened to the manifold as well as the brace rod that runs past the engine. Others have told me that the horn is a more compact type and mouted on the firewall, to the right of the engine.

According to the manual your horn should be a Delco-Remy model mounted to the intake. COE's had the horn mounted to the firewall so it sounds like the horn was mounted in the correct spot when you got the truck.

The original 1953 horn was supposedly the seashell-style horn (first year) and was mounted on the "boss" on the intake manifold, forward of the carburetor (as stated by ddalesr3).

The optional dual seashell-style horns were mounted on the firewall (or other locations) in 1953 and earlier Advance-Design trucks. In 1954, the standard seashell horn (or optional dual seashell-style dual horns) were mounted on the front side of the radiator mounting frame (there ware factory-installed captive nuts for two horns on the 1954 radiator frame).

Thanks to both of you for the info. I am replacing my old style 235 with a newer 261, (1959 chev) so my intake manifold is different. I looked at the old intake and sure enough, there is a raised boss ahead of the carb that has 2 small holes in it. There used to be a thin metal sleeve type bracket that went around the manifold but is rusted out. Does this have anything to do with the horn mounting? Also, can I put the intake from the old style 235 on to the 261?

What year is your "old style" 235 (1953)?

If it is a low pressure 235, the diameter of the intake ports are smaller on the older manifold.

If it is a high pressure 235, the manifolds will bolt to a 261 (maybe - see below).

If your 235 is from a 1953 Powerglide passenger car, it is a real oddball - it would be high pressure engine with two bolts holding on the valve cover. I do not know if the intake manifold port diameter matches the 54-62 235/261. You'll have to tell us, unless someone else had dealt with one of these engines.

You refer to a metal sleeve type bracket. Was this around the exhaust manifold? If yes, that is an automatic choke "stove" that had a pipe from it into the automatic choke on the carburetor (usually on a Powerglide equipped car engine).

For more reliable answers, you might need to post head and block casting codes and/or the engine ID (pressed into the block in the ledge to the rear of where the distributor enters the block).

My old 235, to my knowledge is correct for my 1953 panel. It may even be the original engine, it was cast on Aug. 18, 1953 and is a low pressure engine. My 261 is from a 1959 chev or Pontiac car. But don't get too involved in this, I can simply measure the ports as I have the old engine and the manifold in the garage still. The 261 is now completely rebuilt and ready to go. I appreciate your help, Tim. I really was more interested in getting the correct horn anyway.

Do you have a 1-ton panel or a 1/2-ton panel?

What is the engine ID that is pressed into the ledge in the block, just to the rear of where the distributor enters the block?

Tim, thanks for being so patient with me. I have a half ton panel and I believe it to be a 235. It has a 4 on the floor. The engine ID # says CON3 H164 This number is immediately behind the dipstick tube. I have taken this engine out and found a newer full pressure oiler 261 and this engine has been completely rebuilt.

You'll like that 261. The difference in power is more noticeable than might be expected if you look at the difference in horsepower ratings.

My questions regarding the 235 are not important (ignore them), but a 235 does not seem to have been an original option that was readily available from the factory on a 1/2 ton truck (or even on a 3800 - 1-ton truck).

Get you panel back together and enjoy the ride.
