800 AVS 2
Quality control brand new out of the box was not good , but fixable , this was five summers ago
Was asking questions on the same carb for a friends car that I was working on a month ago
I was asking flow questions with these Annular Boosters , Dyno Numbers etc. on this website , any comparisons along side a Holley etc. along with the same problem you are experiencing
Not a lot of info out there on any website other then running around on the street honestly
This is what I posted on another thread a month ago
"Yes , in the secondary circuit
After verifying fuel pressure like mentioned , fuel flow to the carb , throttle linkage , throttle plates fully opening
Verifying the .104 secondary jets , going to .107 with no change
Removed the secondary jets again , tried carb clean thru the passages with no luck , removed the secondary boosters , flow thru those alone , just couldnt get decent flow thru the passages , even compressed air
Edelbrock Quality Control
Told him to return it back to Summit Racing
Verified by bolting on my old Carter Weber Competition Series 750 cfm on his stroker motor - Ran AWESOME on top end , ran pretty good everywhere honestly - Other then that weighted air door that i hate"

Gonna try it tomorrow plus extensive test for vacuum leaks. But engine builder has already said wrong cam for my application. Sending a new cam better suited. Would appear as per other's comments this was a track car setup, so really for street...lol.
But as Geoff 2 said, new carb won't fix the problem. I have to agree....509 is nice with the right gearing...ohh well. That's mopar university.

I agree with a jetting change. The plug looks very lean.
Couple other things: simple stuff
Are you sure your cable is applying WOT?
I’m not as familiar with that carb but if it’s vacuum secondary make sure it’s opening the secondary plates or opening the vent properly if it’s AVS.
You should have plenty of fuel to the carb without an electric pump but have at it.
If you have extra stuff laying around which it seems you have you could always switch out the ignition system to something simpler to see if it’s that MSD system. A lot of stuff going on there but to me it looks like lack of fuel.

Ya...going to put the Brawler back on today and check hard for vacuum leaks.
Had a buddy(wife) mash pedal for WOT and its there. Also an extra ready run to give a try as well. But have made a decision so will update the post.
OK...I've made an executive decision.
My engine builder buddy has decided to ship me a new can kit. Lunati 60303
Seeing I don't want to put in 4.10's and a 4500 stall, I can't see this combo working at all except for track use not street.
I'll update with 3.55's shortly, but keep the 3500 stall Coan. Then pop the Brawler back on and I should be good. Won't be able to switch for a few weeks as the boss won't let me work in the shop except for rainy or bad summer days now....lol. But I'll update when I get her done.
Now how to degree the new cam with heads on...haha.

Do you know much about the 516s you running? Have they had larger valves installed or port work.
I like the 704 voodoo(60303) with heads that flow well. That really isn't a strong suit of a 516 head. 516s don't flow as well as 915s, 906s, 346s or 452s.

Yuup....we're re done with 2.14 and 1.81 SS. They are closed chamber to brings CR up a bit. Be close to 10.1
I'm checking again today. Will make sure I'm right.. lol
So I'm bad. Ported 906 they are.

That is a good thing.
Get your lean condition sorted out and I think you will like the voodoo cam.
Am working on it now.
Considering this Eddy AVS2 is only 800 cfm, I'm gonna try the largest jet in then secondaries. Can't hurt. Gotta get richer at WOT somehow.
On the edelbrock carb you need to follow the jetting/rod table in the manual so you know where you're at and which direction you are going. The stock jetting is for sea level. The higher in altitude that you are operating the engine, the leaner you need to be.
Yuup. But I'm trying to get more fuel at WOT. So was going to try the largest jet for secondary. And tighten the air flap a bit.
Update.
So I brought the primary down 2 stages as was really rich. AFR 13.7-14.2 Idle and light throttle. WOT a bit better with the largest secondary jet .104. But still hits 18+ when pedal mashed then evens out round 15. And feels like needs more fuel cause it wants to keep going. But starving is gone.
Timing is 21int/35 all in.
So this carb is too small In addition to the cam issue. HG still 5-6....
So will pop the 850 brawler on one more time, but it's cam change.
With gears and looser TC, I'm outage luck with this setup.

800 AVS2 1912 / 1913
.104 is the stock secondary jet along with the stock primary jet
.107 jet is 6% richer on the secondary side
.110 jet is 12% richer on the secondary side
You needed to try at least a .107 secondary jets to see if things would of changed
It reality it doesn’t matter if your going with another camshaft

Have .110 now and not much change?
