I didn't want to say that, I thought I had the only carb. that could talk, and nobody would believe me.

or wet your plugs.

mine can whistle a tune sometimes.

Hey, what about the Predators doesn't anybody care about those?

never ran one on the st., but used them on my drag car and mod. round track. worked great.

I am throwing down and buying a pair of Eddys to replace my Holley 390's. The car was idling weird when I was warming her up just now. I shut if off, took off the scoop and air cleaners, checked vacuum lines, checked the chokes (one of the butterflies had stuck closed a couple of weeks ago), everything looked good.

Fired it up, dropped it into reverse, and BOOM!! Engine dies, backfire and flames. Big flames.

Screw this.

When Holleys run right, they run killer. I LOVE mine when they run right. But they have no sense of humor. I'm getting a pair of Eddy 1403's when I get my bonus check this month.

I just went today and bought a edlebrock,gonna put it on tonight after i put my fresh built heads on, hope it works out of the box like they claim

I dont think any carb will work perfectly 'out of the box', mainly because all engines are a little different. Even two engines, built identically, will need to be tuned a little differently. But your Eddy should be OK as is...if anything, you might have to adjust the idle mixture screws a bit (read instructions), but otherwise it should be OK. Which one did you get?

I've always heard an edelbrock will take more abuse than a holley and thats all I know!!

Please someone shed some light on this for me so I can choose my next carb whenever I decide to build another motor!

Oh and has anyone ever heard of piston rings not seating after 5000 miles? Because thats what mine are doing in a .30 over 350 chevy, rods installed in order, new pistons, lifters, cam, crank, oil pump, you name it, and the compression test with heavy weight oil tells me its the rings soooo .. am I just very unlucky or is this a sometimes common issue?

The 'Brock vs. Holley is IMHO part preference and part application. As mentioned before, typically Edelbrocks are not really the racer's choice. I probably wouldn't choose an Edelbrock carb if I was going to race the car I was putting it in. Hell, even Vic Edelbrock doesn't run an Edelbrock carb on his old Mustang GT-500. So, in that case, (racing) if my only choices were Edelbrock or Holley I'd go with a Holley. But, that doesn't mean the Edelbrocks aren't good carbs. For a daily driver, between the two I'd personally take the Holley....and throw it as far as I could and then install an Edelbrock EVERY time.

I prefer installing carbs, tuning them ONCE and then forgetting about them......forever. I NEVER had that luxury with the Holley's I've owned. They seemed to be a constant pain in the a**. The Edelbrocks I have installed have been a quick easy tune right out of the box, change the jets here, or metering rods there, and then I never had to touch them again...just the way I like it.

Perhaps it's just simply because I really suck at tuning a Holley carb, if that's the case, I'm fine with it. I'll accept it as a limitation of mine and move on. (I'm not a plumber either...that's another one I have just accepted as fact) I've always seemed to be able to get the Holley's to produce good power...they just seemed to lose their tune to often for me.

Now, in fairness, to put some perspective to this last statement so that it doesn't sound more conclusive than it actually is, I've only personally owned 3 Holleys and 2 Edelbrocks. I have installed and tuned a handful of both for other people as well, but really couldn't tell you how well any of them are running nowadays.

So thats about it from me on the whole Edelbrock vs. Holley thing.

As for the ring seating question after 5K miles, how was the motor broke in after it was rebuilt? Is it "blowing by" through the carb, or ???? In other words, what was the actual condition that prompted you to put a compression tester on it to begin with?

In any case, unless you are building a freak beast engine, the carb you put on it, if properly sized for your engine's output, will probably be pretty close right out of the box! Think about how many people really read plugs and make jet edjustments etc on their carbs on the street. Usually you don't need to, and if there really are problems, in general they are often really not the poor carb's fault anyway, Holley, Edelbrock or other

That said, for this post I say Holley rules

Well i got it all together, it started right up woo hoo, seems to run fine, but then again like denny stated, i dont know anything about carb tuning, i did not check the model #, but it is a 600cfm

I've had some experience of Holleys and am quite new to Edelbrocks.
Best Holley I've had was custom built for my Chevy 454 by Chuck Nuytten out of Dallas. 750 double-pumper, choke horn removed, airflow improved to 890cfm max, 4-corner idle, etc. Ran great right off, never needed to touch it, except tweak up the bowl screws once in a while. I may change the power valve soon, and I'm not looking forward to messing with scraping old gaskets off etc.
Have just fitted my first Edelbrock to a Ford 351C, and after reading the instructions, decided to richen it up a stage or two on cruise and power. This was achieved by a simple rod change in under 5 minutes, not a drop of fuel was spilt - impressed the hell out of me!

all i can say is go to the track u might find 1 or 2 eddy's <the street cars. vs the rest holleys or proforms, predators etc

So . . . whadda ya think about running a 600 cfm smog Holley - w/vacuum secondaries - on the rear of a dual quad setup along with an Edelbrock 750 cfm on the front?

Progressive linkage with the rear carb - Holley - as the primary.

Best of both worlds for street use and measurements show it's a do-able deal.

that would be a pain in the a*s to keep in tune.
