quadrajet replacement

Holley made a direct replacement for the Quadrajet called a spread-bore pattern. The nice thing about the Holley was that it was pretty much a direct replacement and you could easily change the jets in it to adjust for optimum fuel usage or economy. They are still out there. I believe it came in 650 and 800cfm sizes, maybe more now.
Hope this may help, Happy Trails Bert

You can also find carbs that have already been rebuilt on Ebay. I'd do the repair kit.

If you decide not to go the rebuild route on the one you have, contact Edelbrock for the correct replacement and then shop that number on the web.

I've rebuilt dozens of these, which means anyone with a couple of screwdrivers, a pair of needle nose pliers, half a brain and can follow instructions should be able to as well. No black magic here.

Although the Holley AFB is a better carb... You'll need to be able to bend and move fuel lines. Normally you would fill the tube with sand and bend it, but I recommend getting a tube bender and flaring kit instead.

Would it be worth upgrading to a fuel injection system? Just a quick at Summit Racing shows a decent looking kit for under $800. I don't know if this is all inclusive, it looks like it might be.

Why do you need to replace it? x3 on finding a good carburetor repairman and getting an informed estimate. Look for an old-timer or a racing shop. Having said that, an expert carb mechanic is not cheap. I just dropped $700 on a rebuild that was needed for my HR to pass emissions. It was a lot but the results were outstanding. However, my last motorhome, a '72, was exempt from emissions. I took out the original carb and put an Edelbrock on it. I was much happier with it. It was very easy to work on and tune. I sometimes wish that I could do the same for my HR.
