So I was researching carburetors and came across a video in which a gentleman was wrenching on a old Ford that had been in the family for 4 generations. The reason I posted this is because the carburetor was clearly old as it had a glass window on the carburetor.

Does anyone have a Ford like this? Or, have any information regarding this?

THOUGHT: Why did this feature get phased out? It struck me as genius, and highly practical.

 

Lots of old Fords were built using the 1 barrel carburetor with a glass bowl. Engines like the 215 and 223 used them but not all. My '53 Ford has the boring cast bowl.

 

When I saw this I knew that a few engines would have them, which was so Practical. Not having to take the carb apart to see whats going on inside. It's freaking brilliant!

Do you by chance know why they didn't keep this feature? I mean, I know that not all vehicles are carbureted- which is part of the reason I'm sure. I can see this being used on 2's & 4's I would prefer my Holly or EB have this to save me time of taking the damn things apart.

 

I'm not sure why that wasn't done more often. I wonder though if it just becomes useless over time as the gasoline and vapor in the bowl causes deposits to build up?

BLP made some of their Holley billet metering blocks out of clear plastic. I don't know if that was just for display purposes or if they were functional.

A couple of different times I've made see through spacers to use on my dyno so that I could stand there and see what was happening inside of the intake. The first one was for a two barrel made out of a piece of acrylic that was 1 inch thick just like the adapter. It was neat. I would stand there and shine a timing light through to freeze frame what was happening at say 6000 rpm wide open. it was very interesting and anybody who says that they have what's happening inside of the running engine all figured out just hasn't done that experiment. It worked great but then it shattered into a bunch of pieces after a heat cycle.

 

Yup! well known on just about everything up until the late 50's/early 60's when it all went away!
