New Carb - Whole new ballgame!

My 572 BBC supposedly came dynoed with a Quickfuel 880 Mechanical Secondary carb(BS because it had factory airbleeds, jets and powervalve which were all changed out after the fact).

Anyway, I was never super impressed with the performance of the motor and throttle response of the card since day 1. After wasting a lot of time and effort on my part, one of my racer friends told me to call Jeff over at AED. I gave him all the specs of my motor and he recommended a Modified Holley 850 HP that would flow 1050cfm. It was a lot of money, but paid extra to have it set-up, wet tested and tuned. They said I would most likely just have to bolt it on and man they weren't kidding! I didn't even have to adjust the idle! The car sounded totally different, revs were quick and crisp. Had it running for only 5 minutes in the driveway and had to pull it in the garage as it started to rain. Came home from the work the next night and took her out for a ride and all I can say it HOLY F*^K!!!! It is like someone flipped a 250hp button. When I got on it before the car stuck to the road like glue, little to no tie chatter or spin - now I can't get traction at all - even breaks the tires loose in 3rd gear - crazy scary insane to say the least!!! I cannot say enough about what they did to wake up the sleeping beast! This is what I was originally expecting when I hit the throttle for the 1st time!

I would recommend them to anyone on the fence and having carb issues - I still cannot believe what a difference it made. Worth every penny and then some!

Re: New Carb - Whole new ballgame!

They are definitely the best. They also have a deal where if you buy a carb from them and you are close enough you can take it there and they will put it on the chassis dyno and tune it.

Re: New Carb - Whole new ballgame!

I had an Edelbrock 600 on my .060 350 when I bought it. I added a Trickflow top end kit. It was an improvement over the smog 882 heads and performer cam. I jetted the carb to its max setting and it still seemed blah. I put on a Holley 650dp and noticed an improvement right away, but it still needed some tuning. I got it close, well I thought I did. I mostly tuned out a lean stumble I had and I thought it ran great. Then I took it to the dyno. I was lean in the secondary and I still had a slight stumble on part throttle cruise. I slowed my advance curve down and rejetted the carb. I went back and made another 11hp, however, I'm still lean in the secondaries according to the Air/Fuel readings. I went up another two sizes and it runs so good now. There is nothing like the feeling of getting the right carb dialed in.

Re: New Carb - Whole new ballgame!

Greg, Your original carb may have been contributing to the over heating problem
you had. It will be interesting to see if the temp changes now.

Re: New Carb - Whole new ballgame!

The guys at AED are great. They even emailed me on a Sunday with their recommendation. Mine has been perfect for years now. I never have to mess with it.

It's amazing what a correctly tuned carb can do! You sure have the purdy factor going on there too. Glad to hear you had such great results.

Hope that's true! I don't live far from Richmond. I have a mongrel AED carb on my 69 right now that works well, but I'd love to pick up something specifically tuned for my motor and see what she'll really do.

Re: New Carb - Whole new ballgame!

Looks like annular boosters ?

I thought about going with those on my 850 XP.

Re: New Carb - Whole new ballgame!

I run a 850 annular and it has been the best choice so far over the down leg boosters.

Annular boosters need less fuel than down leg boosters

Re: New Carb - Whole new ballgame!

I run an AED on my 461 and wouldn't recommend any other carb for a performance application.

I wish I could. Just spent $185 for that and it doesn't get enough air unless I take the filter out and run it open. Short of cutting a hole in my hood, I am out of options

Re: New Carb - Whole new ballgame!

One thing I will say - there is a lot of controversy on punching holes in the throttle plates when I was trying to get the most out of my old set-up. This carb from AED has the primaries punched and with the night and day performance I've gotten from this upgrade, I'd say they know what they are doing!

That's interesting that you say that. Mine had all four butterflies punched when I got it. I should have left it, but I wanted it "right." Now I'm chasing a few things. I'm about to throw 37s in for the accelerator pump nozzles to see if that will help with a slightly lean condition when I nail it. I have 35s in it now with hollow mounting screws. In theory the drilled plates only help idle though. I think I'm going to throw the plates I had in it back in if the new nozzles don't clear everything up. If it works, it works.

Re: New Carb - Whole new ballgame!

The new Holley XP body has adjustable air bypass built in, no more drilling holes in the throttle plates.
AED should use that new casting.

Re: New Carb - Whole new ballgame!

Dont believe in using them....mess around with those air bleeds. Jeff will get it perfect
