Im almost done with the necessary chassis work and have been thinking a lot about engine mods. Next couple of months I may be spending up to 500 bucks on my 289 2V.Im lost in all the types and makes of intakes and carbs, and terrified of getting something that is unreliable. Id rather have my reliable 2 barrel than a pain in the @$$ 4 barrel. I do want a 4 barrel system, and am happy spending that $500 on an intake and carb. So can I rely on you guys to give me your opinions on Holley Vs Edlebrock Vs Demon Vs Autolite? I will need an intake to go with it, and am looking at trying to make 300hp street engine. (I will eventually get a new cam and headers, but I am thinking about the carb and intake first). The general feeling I get is that edelbrock is less powerful but more reliable? Autolite are great but expensive? I would buy second hand, but Im worried about reliability, and my budget allows new. Thanks, you guys are great ------------------

As it stands I am heading towards a holley DoublePumper600CFM and an edelbrock performer RPM intake. Do I need electric or manual choke? What about my automatic C-4 transmission does that matter to the carb?Thanks again!!  I know you guys love talking about carbs!!

For street and ez of use I vote Edlebrock.I have one on the Fb and have never touched it nor had a problem..now if you going for max HP or Racing use the Holley..but for the Avg. streeter the Edlebrock is my choice.
Oh and I have a Performer RPM under it.

I can see that the basic sense that holleys can be trouble but they make good power is true. I may avoid them then.
300hp should be possible with edelbrock, so long as everything else works good right?I guess the unkown is the driveability aspect, does it go when I press the loud pedal. Pierre over there in France seemed to think that his holley hauled @$$ while his edelbrock left him scratching his 'ed. I hear a lot of people that tell me that they never seemed to get more than a couple of runs out of the holley before something broke or leaked. thats not what im looking for. anybody use the new street avenger?

I have been doing a lot of looking around for a good carb/intake combo too and I've been leaning towards a Holley Street Avenger carb and a Weiand X-elerator intake.The carb is supposed to have all the power that Holley is famous for along with the ease of mainenance that Edelbrock is known for. As far as the Weiand intake... well with a 351-2V, I'm kind of limited on my choices... It's either that or the Edelbrock performer intake. ------------------

>supposed to have all the power that Holley is famous for along with
>the ease of maintenance that Edelbrock is known for.Hmmm, the Street Avenger is just a typical Holley with few optional
features (center pivot floats, power valve blow out protection, quick
change kit for the vacuum secondary springs, etc.). It's a good carb
but you still have to pull the bowls off to change the jets or power
valves and the air bleeds and power valve channel restrictors are
still fixed area. Also, the potential for leaks is still there due
to the modular body plus metering blocks plus bowls design (the
vertical gaskets can dry out and shrink over time, causing leaks).
The newer red Holley gaskets should be much better than the old paper
gaskets, in that regard, but you'll need to verify Holley actually
uses those gaskets in the particular carb you want (some do, some
don't). The 4010 Holleys were much like an Autolite 4100 and had a one piece
main body with top lid and were, by design, much less likely to leak
but Holley dropped that line of carbs. Autolites and AFB's are also
less likely to leak due to their design. The AFB's also allow easier
fuel enrichment and jet changes (no disassembly required). There are
kits that allow Holley jet changes without disassembly but your still
stuck pulling the bowls to change power valves. >As far as the Weiand intake... well with a 351C-2V, I'm kind of limited
>on my choices... It's either that or the Edelbrock performer intake. The Weiand Xcelerator for the 351C-2V works just fine, particulary with
some compression (I run Aussie 2V heads to get the compression up) and
cam. You must port match the heads to the intake though, as the
Xcelerator has larger ports than the head. This is best done with the
heads off the engine but I have done it on an assembled long block. I
stuffed a bit of newspaper in each port, near the valve guide, then sealed
off the port with modeling clay. The clay keeps any grindings out of the
enigne and the newspaper keeps the clay from pushing too far back in the
port. A valley cover made out of cardboard, taped to the block, will keep
that area clean. I had an assistant stand over me with a shop vacuum
which realy helped to keep the grindings down. After I was finished, we wiped everything down and removed the clay and
installed the intake. If you use a valley pan gasket, you'll need to
trim that too using a dremel. After a few hours of run time, I did an oil and filter change, just to
be safe. Dan Jones

You mean my new-in-box 750 Annular may still have the paper gaskets? 
Da*n Holley is stupid....
I guess I had better pull it apart and check.
AED (an aftermarket Holley parts outfit) has re-usable blue gaskets that local racers use also, and they are cheaper than Holley gaskets.------------------

The biggest problem with carbs is that folks think bigger is better. This is absolutely not the case. If your 289 is stock, you definately do not need a double pumper carb. In fact, you'll only need a max of about 500 cfm at WOT with your engine and that's after you add headers. The Holley 1850 (600 cfm) universal carb will work fine on your current engine. You'll also get better throttle response from a Performer intake, not the RPM version as it raises the useful RPM range.

Not really, they are very smart. That way they get you to buy more gaskets. ------------------

My 289 is stock now, but it wont be in the future. I understand that big carbs and RPM intakes might not work great straight away but I cant afford everything in the first month. I have to pace myself. I dont want to buy anything twice. I am really leaning towards an autolite, but if the edelbrock is a capable carb for 300hp then i may go that way. You guys have scared me off holley for the time being.Thanks ------------------

I use Edelbrock because I got a deal on the intake/carb combo. The tuning capabilities are a little weak, but it works pretty good on my combo.408W
750CFM electric choke
Vic Jr intake
Stage 3 Pref RPM heads
Long tube headers into 3"
C4 Makes about 400HP with a goal of 500HP when I get the MSD on it.

Be sure and check ebay for parts to begin with. You can pick up a used carb and intake fairly cheap and when you get ready to upgrade, sell your old stuff. You can get intakes and carbs all day for $100 or less each. A $19 rebuild kit and a $3 can of aluminum spray paint later and you'll be showin and shinin.

What do you guys recommend for a 351W that's a little hopped up (280H cam,9.5:1 Pistons)?
I heard that you could get away with the 600, but that sounds a little under-carburated for me.

780  List# 3310-1, 4150 w/ vaccum secondaries... that's how I can get away with it. A dp of similar size would be too much for a smallblock IMHO

Thanks for all the thoughts.
Funny thing happened. While I was under the car I this weekend I think I decided to go with a dual exhaust and headers first, then maybe do the intake and carb stuff sometime in the winter. It will probably end up being edelbrock or autolite, I've been hearing too many bad things about holley for street use. Now, headman long tubes, or tri-Y?

I am (was) running a 750 Edel on my 351. I put it on to replace my old 4160 Holley, only because it was the only thing I could find locally except another 4160, which I did not want. Looking back on it I wish I would have waited on a holley. The finish on the Edel has spotted and looks bad. One thing to look out for with the Edel is the carbs are jetted different depending on if you order it with a manual or electric choke. The manual choke model is jetted much richer.------------------

I also have been looking at the barry grant road demon. So anybody out there have opinions on them? They look good but cost a fair amount for a street carb.I will almost certainly be doing the exhuast first I found my poorly fitted single exhaust system rubs on the driveshaft and the shock absorber. I already patched one hole in it at the Y section. Its time to make some sweet noises

Its a good idea to go with a good exhaust system first,thats always a huge help on a Ford.And the type of tranny you have DOES matter as you will need a hookup for your passing gear kick down if you are running an automatic.I would also use a vacuum secondary for automatic and a DP for a stick.I will also vote for the Holley,I have used several over the years and never had any trouble with them,.but a good inline fuel filter is a must.------------------

My decision came down to a Street Avenger or the Demon and I went with a Demon 625 for $325. A little more than the Avenger but the quality sure looks good on the Demon, Have not installed it yet but will be soon. ------------------
