I've tried Edelbrock. Now I've tried Holley. Don't think I'll go back to Edelbrock.
I was having a problem with the secondaries on the Edelbrock - when they open, the engine leaned out, it would stumble. No combination of jets/metering rods/metering springs that I tried even improved it. Nothing Edelbrock suggested improved it.
After talking with another member, I decided to get my feet wet with Holley, and go with a Street Avenger. It included 3 secondary springs. I had to use the black one. Now the transition to the secondaries is nice n smooth. That alone makes it worth it. Some other things improved. With the Edelbrock, when cornering hard - and just how hard can one corner in a 48 year old solid axle truck - it would stumble. The Holley doesn't do that. It seems to rev faster and feels a little more responsive. Jet changes are a piece of cake. On the Edelbrock, the whole top of the carb has to come off. That includes the air cleaner, fuel line, linkage clips, in some cases parts of the choke. On the Holley, it's just 4 screws and a fuel line. The Holley also has so much more available for tuning.
So, long story short, in a few days, I have the Holley running better than I could get my Edelbrock to run in 7 or 8 years - it's all blurred together now.
I kinda wish I had gone with a Holley to begin with but I like to have experience with many things so I can give informed advice.

Charlie,
I did the same thing. Then I replaced the SA with a demon. Like the demon much better than the jump. :-)
What a money pit, but I guess you learn something new every time.

I bought a street avenger for a Camaro that I had.I really liked that carb.I had it on the car a couple of weeks and changed cams.
It comes with the blue gaskets,so changing power valves took all of 5 minutes. I would buy another one if I was looking for a carb.

| I'd seen a real deterioration in the quality of Holley products over the last few years. Used to be a fan of their products. I was involved with the Company back in the '70's when they developed their intake manifolds. They were fun to work with then, the engineer who ran the program (Mark Campbell) later went on to become Chief Engineer at Crane Cams. I sincerely hope the newest management at Holley takes the quality issues seriously. Between the disaster that was the first "Pro-Jection" with it's horrible electronics and the leaking, non-working junk of the last ten years, they have their work cut out for them. I have replaced my last Holley on my Ranger with a Demon, which works, doesn't leak and stays in tune. Charlie, They cornering issue has been a constant with Carters and Edelbrocks since the Dawn of time. My 65 GTO had those issues 40 odd years ago.

Hopefully I have none of those problems. I was planning to do fuel injection this year but I'm so far behind as it is. With 2 months until Columbus, I just want something that will not stumble and accelerate smoothly when floored. And that seems to be what has been achieved.
I would like to have picked up a Demon locally at a reasonable price, but the Holley is all I found. I don't really like to mail order these sorts of things.
It was raining today. It definitely picked up some bottom end. It spins the tires much more easily.

| Charlie - If your Avenger carb didn't come with the STEEL needle and seat assemblies, consider getting some. They can be bought from Holley 2 per package in the .110 orfice size for a decent price. In recent times I have had all sorts of float level stability problems - both with the Demon in my bird - and the Holley in my 442 - the current flavor of "gas" is not too kind to the Viton needle/seat arrangement.

| Steve. John thinks it's the alcohol in gas that does this. I agree. Does a number to the accel pump on my teapot too. Funny part is, John raises soybeans, guess what they make out of those!!

Hey, hold on there Pegleg. They make diesel fuel from my soybeans. The corn is used for ethanol. When they finally take the entire US corn crop for fuel production, you won't have any more corn flakes for breakfast or corn fed beef to cook on your outdoor grill.
