Is the 7041205 carb real hard to find?

Corvette Only part, per Mitchell interchange guide.

This will be a VERY difficult to find carburetor. As Bill mentioned, it was used only for Corvette applications. Besides that, it was used ONLY for the 1971 Corvette with 454 and manual transmission. This all means that there were probably only about 3,000 of these carburetors ever used for PRODUCTION.

The application was SERVICED from September, 1970 through June 1977 by carburetor GM #7047116. This was the on-box part number and I don't know if the carburetor supplied within carried the 7041205 part number, or not. In any event, even if this carb carried the original part number, I doubt that very many were made.

All this means that there were never very many of these carbs to begin with. Some may be still out there in rebuilder carbs used for other applications (rebuilders don't care much about specific carb numbers or in using those numbers for the same application that they were initially used for) or they've been scrapped as non-rebuildable cores.

Another Q Jet Question

Hi Guys,
How difficult is the 7040204 FF carb to find. This should fit a 1970 with the 454 engine rated at 390hp.
Thanks,

The 7040204 carburetor was used across all Chevrolet models in 1970 for all Rochester-equipped big blocks with auto transmission. That means that there are a LOT more of them "out there" than for p/n applications uniquely applicable to Corvette.

Still, big blocks were not, by far, the majority of installations for 1970. Many of these carbs have probably become "lost" in rebuilders core stocks over the years. So, while they're "out there", it's very hard to find them in the "sea" of rebuilt carburetors. Of course, if you do get lucky, then you get one at a bargain basement price compared to what you'd pay to a Corvette carburetor core dealer for just the core, alone. The logistics of finding the carb this way are just too burdensome, though. I mean, asking your local parts house to order 200, or so, 1970 Corvette with 454 and auto trans rebuilt carburetors so that you can go through them to find the ONE that MIGHT have the correct part number on it is, to say the least, not going to make you any friends at your parts house.

Also, many of these old carb cores have been discarded as non-rebuildable by commercial carb rebuilders. You see, a rebuilder is not going to invest any serious money or effort to rebuild a core that is damaged, worn out, or needs any serious work to make it usable. Those sort of carbs go in the scrap bin, REGARDLESS of what numbers are on them. Restorers might be willing to invest just about any amount of money to restore a rare carb to functionality. However, a commercial rebuilder won't and few, if any, are going to have someone spend the time to save the few "rare cores" from the "sea" of nondescript ones.
