[/QUOTE] I’ve had a lot of holly carburetors a part before. But I have never seen any baffling inside like this before?[/QUOTE]

Factory installed on OEM '71-72 Holley for then-new Evaporative emissions regulations. Reduces bowl volume so less grams evaporates after shutdown.
Also came on my over the counter GM 4803 Holley.
I found a quote in an old Holley book. If you want it, PM me and I'll scan it for you.
Just one more example of a so-original car, even including the brass fuel filters.

Wasn't sure if you were surprised by the float ? Guess not. The GMheritage site has a ton of information on your LT-1.
All good, have fun.

First, as you'll see, you need to undress it!

The video was done on phone, I downloaded it to my computer, put it up on Utube, and then put it in here as a link. You might well be able to load it to Youtube direct from your phone. The forum wouldn't take it direct from my computer, wrong format.

Good luck! I was wondering if the TI ignition was still viable.

Troy, you can go here and get the Vehicle Information Kit on just about any Chevrolet made since 1913.
https://www.gmheritagecenter.com/gm-...tion-kits.html

Here is the one for the 1971 Corvette. (it's non-specific to a particular VIN)
https://www.gmheritagecenter.com/doc...t-Corvette.pdf

Download it and save it to your computer and it will make a terrific reference guide for your car.

Good luck... GUSTO

I found the documentation on the strange Holley bowl stuffers you found. Just one more authentic original piece on that car. Here is an article that mentions that they are original and why:
From a 1976 copy of Holley Carburetors & Manifolds by HP Books & Mike Ulrich & Bill Fisher:
"Evaporative Emissions - In 1970-71, total evaporative emissions allowed from any car were six grams per hot soak. In 1972, that allowance was reduced to two grams per hot soak. It should be noted here that this reduction in allowable evaporative emissions created the need for reducing the bowl capacity of some Holley Carburetors with bowl stuffers."
