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.
