Holly or Edelbrock

I have the Holly on my 302. Easy to work, setup was no problem. I have changed the jets trying different things and it takes a couple of mins. to do. It works great with no problems.
 
I'm running an Edlebrock on Red right now but considering swapping it to an Holley. Shag will be Holley ran.
 
I have that Edelbrock and it works fine on my 302. I replaced a leaking Holly double pumper once with an Edelbrock out of the box (never changed one before) it was perfect no adjustments, but hey I am not an expert and they all might seem perfect but could use some tweeking.
 
Just my opinion, but I can't stand Carters (Edelbrocks). At the price point you are looking at I would consider the Holley but I would step up to the Holley 0-80783C instead. It's more money but is fully adjustable. At the same cost as your original choices I would pick the new Summit carb. It's all Holley compatible guts but is in a different casting, more like the Ford 4bbl as far as the no leak design but with the great Holley parts. It's pn #SUM-M08600VS and is here on their site http://www.summitracing.com/parts/SUM-M08600VS/
 
+1 on the Summit carb. I'm running one, and it's been trouble free, bolt on. Probably could do a litte tuning, but the plugs look pretty good.
 
Nobody has asked yet what the intended use of the car is. If it's just street driven, and you don't know much about carbs, go Edelbrock (or Carter). If it's going to see lots of track time and you are pretty familiar with carburetor operations, go Holley.

I have an Edelbrock 1405 (jetted up) on my '66. I have a Holley DP on my '69's 408.
 
I have an Edelbrock and I like it well enough. It's reliable and very easy to tune. There are some tunability drawbacks, but you don't usually run into them during normal street driving.

That summit carb is supposedly pretty slick for the price. If it had been an option when I was building my motor, I probably would've picked one up.

As is, I'm considering a Demon or QuickFuel in the future for increased tunability. It's going to have to wait until I have more $$ though.
 
I haven't had the Summit-Holley but it looks like a good carb. I've always run Holley's and I don't know why people complain about them leaking. Never had that problem, also I don't think they are hard to tune. Nice thing about Holley's is everybody but Edelbrock is copying them and tons of stuff is available for them if you do want to tweak them. They do work on a street driven car too but they don't like really really cold weather, I've had them on my DD's and lived in the Chicago area and they can "ice" up and idle rough in really cold weather. I say you can't go wrong with a Holley, my .02 cents.

my thoughts exactly.

i have an edelbrock on my shop truck & a couple of the "cruiser" street rods in the past. the one on the shop truck was set up when new & hasn't been touched in almost 10 yrs. same for the one that was on my 40 coupe.
my "built" motors get the holley style carb. as others stated , much easier to get parts to fine tune for your application.
 
My 408 was built by a professional race engine builder. I told him I wanted to go with the Edelbrock Thunder AVS carb (because it was silver / red / and black :)). He was reluctant at first, recommending Quick Fuel, etc. But, he went along with it.

He dyno'd the engine and the carb worked like a charm right out of the box. No tuning required. Perfect A/F ratio across the board and it ran strong. He was happily surprized by the results.

It developed 524 HP and 516 Ft-Lbs. It's not a tame engine by any means, but is quite streetable. It starts easily and has behaved better than I had expected. Once I got the electric choke dialed in, it's been hassle-free.

Just another reference point for you.

I put a Carter AFB2000 on my El Camino back in '90. I built the 383 in it - cam, heads, intake, headers, etc. But, the compression ratio came out too low - about 8.3:1 or something like that. That Carter occasionally is hard to start and there is a definite and bad off-idle bog that I cannot fix. I think it's because of the low CR. I've read that this can mess up the signal to the carb and make it stumble like this. I've rebuilt it twice (mostly because of trash in it), but these symptoms still exist. On the road, though, this engine runs like a champ.

There's another reference point for you.
 
I have an Edelbrock and it is fine for street use. I always read that Edelbrocks are eaiser to use and Holleys are betters once you get them tuned. A few years ago, I didn't have a clue on how to tune a carb so I bought the Edelbrock. I have it tuned and it runs smooth, is reliable, and clean on my weekend cruises and weekday drives to work.

Now that I have a wideband O2 sensor installed and have been learning how to tune a carb, I wish I would have bought a Holley instead. The Eldebrock is fine, but I wish I had a little more tuning options.
 
Is there any advantage of a Barry Grant carb over a Holley brand carb? I don't know much about carbs but have heard good things about BG carbs.
