HI All... Just picked up a 1966 327 L79 roadster. The original Holley carb has had issues for years and definitely needs to be pulled and rebuilt. I'd like to switch over to an Edelbrock AVS 1906 carb(650cfm). Anyone else running this in their L79? What do I need to consider beyond running the new fuel line and adding a fuel filter? Will I have air cleaner clearance issues?
Part of the reason for the switch is wanting something that requires less maintenance. I already have 2 other cars with the carb on it, so I am very familiar.
Crowthern - Welcome to the Corvette Forum. I still have the #3367 Holley on my 66 L79, runs fine but on my 65 L75, I swapped to an Edelbrock #1406 many years ago and it also runs fine.
Can't say I've heard that much discussion on the AVS series but thought the secondaries are mechanical on them. For my kinda street driving, I lean towards a vacuum operated secondary.
In any case, again Welcome and you do know that New Members are 'Required' to post up pics of their Corvettes...right?

Were you able to use the stock L79 air cleaner base with the Edelbrock carb?
Lucky - with the help of an offset plastic carb adapter. My 65 300 Horse Coupe lost it's original dual snorkel air cleaner long before I bought it in '85 so I used a 66 14" chrome top 66/67 air cleaner but needed the adapter to
bridge the difference in diameter. Then later on, happened to run across a repro 64/65 dual snorkel air cleaner and it just took a little more 'adjustment/grinding' on the plastic carb adapter to work out.

Nathan,
Welcome to the Forum. Your L79 is one of the sweetest engines Chevrolet ever produced...and, the original Holley was specifically designed for you engine. Before you give up on it, I would recommend you give a call to Phil Cancilla at Custom Rebuilt Carburetors in New Jersey (732-356-4333). He has rebuilt many Holley 4160 carbs for me over the years and they come back as good as new. His turn around time is terrific, as well. The Holley carb is a wonderful piece when rebuilt and tuned correctly.
Thanks for the feedback and suggestions. I do plan to get the Holley rebuilt, but also have access immediately to an Edelbrock 1906, which I am already familiar with. I have a host of other projects on the car to work on as well. I can't really drive the car with the carb as it sits. I'll very likely switch it back somewhere down the road, but for me now, this is the path of least resistance. Already learning about all the other things on the car, the Holley will just have to wait for a bit.
But, back to the original ask. Anyone that has any lessons learned with that setup, it would be appreciated.
I don't remember the model number, but I used an Edelbrock AVS on an L79 intake one my 60 while I was waiting for the original dual quad setup to be restored. Carb ran great on there and made a good bit more power than the dual quads but that aside, I did have to open up the secondary side on the manifold to get enough clearance for the rear butterflys to open
