Ok – so I bought two of these carburetors, based on a favorable past experience with a new Edelbrock carburetor years ago. I put one on a 1979 GMC C-1500 Heavy-Half, 350 V-8 that I was making some updates on, and also a 2nd one for my boat – a 351 Windsor inboard/outboard. I just wasn’t in the mood to fight the old carburetors that were on these. So, the carburetors installed easily. A vacuum port plug was provided, for the back of the caruburetor, if your vehicle doesn’t have power brakes. This seemed odd to me, as virtually everybody has power brakes nowadays – so to me, they should have provided a hose nipple to put into this port – not a plug (although, for my boat, that worked out great). The paperwork says there was supposed to be a DVD in the box but there wasn’t. These carburetors worked flawlessly, right out of the box, with ONE exception; neither will let me adjust the idle low enough. I have all vacuum ports utilized or plugged, and I have no vacuum leaks anywhere that i can see, but I can only get the idle so low, then the screw no longer makes contact with the carburetor control. I called Edelbrock’s tech hotline, thinking there must be an adjustment somewhere else on the carburetor that I just wasn’t aware of – and they told me I must have a vacuum leak. Not much help. I told them I had two and BOTH are exhibiting the same problem/issue, but I was told I must have a vacuum leak, as the carburetor should be able to idle low enough to stall. They suggested I mess with the mixture screws – but I can’t see how that could offer a valid solution and would only result in my mixture being messed up, and I’ve never heard of messing with the mixture screws to lower an idle. Anyway – I like the product and will continue to try to get them to “idle down” but – we’ll see I guess. And – if you call the Edelbrock hotline – they give you an option to dial or say 0, and they’ll call you back – but that didn’t seem to be working. A “knit” and I told them about it. And, the guy told me they quit supplying the DVD over a year ago. This is no real problem, as there is an excellent tutorial on YouTube. I am disappointed though, with not being able to “idle down” either of these carburetors. BOTH are exhibiting the same phenomenon. But – I like the product regardless.

I bought this carb to replace a Holley. I’ve always had Holleys on the 351M in my truck, but decided to try the Edelbrock because of the fuel delivery method on the AVS2. I could not be more pleased with the improvement. The Edelbrock responds immediately to the gas pedal. It does not stumble at all and accelerates smoothly and strong. The overall performance has improved dramatically since installing this carb.The engine is also running much more smoothly and even the exhaust tone is better than with the Holleys. To be fair, my guess is that I was just never able to get the Holleys tuned just right so this is not being critical of Holley carbs. I just lack that skill set to tune those carbs and the Edelbrock seems to be good out of the box. I only had to make slight adjustments to the idle speed screws.Another plus for me is that the Edelbrock is wider but not as deep as the Holleys. I have an electronic distributor that is larger than the OE distributor and with the Holleys it has always been really tight between the carb and the distributor. With the Edelbrock, I have at least an inch or so between them. It makes adjusting timing easier. I also added the Edelbrock 9265 heat insulator gasket which lifts the carb maybe a 1/4 inch which also helps with clearance.I gave it a 3 for installation ease because on the Fords it requires another kit (1483) for the C6 automatic transmission kick down bar to attach to the carb. It took some adjusting and getting a longer adjustment screw for this, but with some tinkering it works perfectly. Nothing really hard about the install, but it does require some fiddling to make everything work smoothly on the Ford.I’m extremely pleased with this purchase.

Installed this unit on a 1972 Cutlass Olds 350 Engine as a quadrajet replacement. The performance is outstanding right out of the box. I had never swapped out a carb before but the online tutorials and design make this a great simple upgrade. Had to purchase an additional spacer block to get enough clearance between the accelerator linkage and manifold, so you may want to double check your clearance before ordering. Highly satisfied and would definitely recommend!

I have always used these carbs, as new builds and replacements.

Great carburetor this is my third AVS2. I put this on my last 2 vehicle and just now on my third one. All were street rods.

Carb is fine except when parking on my sloped driveway, is is hard to start from flooding. when purchased in 2020 it was hard to adjust, till I read the instructions and said to use an adapter for square bore to spread bore. That cured the vacuum leak at manifold that I fought for months. Still floods when first start up. I have not adjusted the float, due to having to unseal a new carb. Is is on an 1986 C10, with 350HO crate engine! Does scream after cleared out and gets 6MPG but quickly!
