I am running a 355, 10.1 comp, full port and polished and 2.02 and 1.6 valves 220 Duration, .540 lift 6500 rpm, 5 speed, 373s, street strip use
I do not know why but I do not like Edelbrock, any good brands under $400

How about a Holley Street Avenger 770?

Vacuum secondaries aren't a good match with a T5. A double pumper is a much better choice.

If you need to keep it below $400, you're probably looking at used.

Just run the lightest spring. I didn't find it annoying. Then again, that car didn't have a T5, it had a T-10, so no overdrive.

The secondaries won't close immediately between shifts. Turns WOT events into speed shifting, which T5's don't tolerate very well.

Ah, I wasn't thinking of that. Well, it'd give the OP a good reason to get a stronger trans.

I think a 770 cfm is to big. Is this a good one?http://store.summitracing.com/partde...5&autoview=sku What is the difference between holley and Edelbrock carbs? Is a choke needed I live in AZ?

you dont need a choke, the car will be a little tricky to sat when its cold but nothing major. The edelbrocks are old technology and are garbage, dont even consider them.

I second the mechanical secondaries,

as for price, maybe check out ebay, sometimes there are some really great deals on slightly used parts there, and some new.

You might not "need" a choke, but it certainly is a lot better to have one for a street car. Allows you to start and drive the car cold and still have the main circuit lean enough for decent economy when the engine is warm (although, doesn't sound much like a daily driver engine).

The Edelbrock Performer carbs are a slight update of the old AFB design. The secondary throttle blades are opened mechanically, but air flow is controlled by a non-adjustable air valve. Similar but slightly different issue with WOT operation and shifting, except there will be a delay in the secondaries opening after a shift.

sorry, i meant to have typed 'you dont "need" a choke', for a DD its a good idea. For a weekend car like mine, its not so much on an issue

Summit has a new line of carbs they are selling under there own name. They are an updated copy of the old 4010 holley design. I just put the 750 vac sec one on my 350. I have only run the car for a few hundred miles so I can not give you a good review on how it will run long term but I have been pleased with it for now. I have it on a 350 with an air gap intake and roller cam. They reason I bring this carb up is you said you were looking for something under 400 dollars and I got this one for around 230 dollars brand new. I think they offer it in a manual secondary.

They do have a 750 cfm mechanical secondary version available. On sale for $300 right now. Manual choke, though (electric choke conversion available for another $50).

I've never had one of those 4010 model Holleys, but I haven't heard glowing things about them, either. You have to remove the entire top to make a jet change. However, it might be close enough out of the box not to worry about it.

If you're willing to try it to stay within budget, it's probably worth a shot.

Sounds good but with the summit name on it I am not too sure about it I will try to find some reviews.
It looks like a 750 is about the right for my combo.

I have not had much experence with the carb yet myself. but as far as jet changing there are only 6 screws to remove the top and change the jets. The one I got was right out of the box for my app. But I am not running anything wild on my car so a 750 should have been to much carb for my motor but I in fact had to fatten it up, jets were OK just had to richen the idle circut. But like I said I have only run the carb for a week so I can not give you a full review on how good of a carb it turns out to be, all I can tell you is it is doing OK right now.

You can bet the farm that the only thing "Summit" about it is the name. It's made by Holley.

That would be my recommendation.

I would take five 7's advise and stay with the mech secondaries. I bought a brand new holley for my car. It was a vac secondary carb, I will tell you first hand they dont perform anything like the mech secondaries behind a manual trans. I took my holley off after about 10 miles because it totally sucks to stomp the throttle and wait for the secondaries to open. I went back to my 4106 edelbrock. This is the carb I purchased and now its back in the box http://store.summitracing.com/partde...5&autoview=sku

Waiting for the secondaries to open is a matter of tuning, best accomplished with a Quick Fuel Technology adjustable vacuum secondary housing. If you can feel them open, then they are actually opening too soon.

Waiting for the secondaries to close can be downright scary.

I have to agree with five7 if you feel the secondarys come in, then the carb is not set up right. Vac secondarys are great for street cars and limited strip. When you get it right you will love it but getting one right is all about trial and error because no two motors are the same. I am a 25 year ASE certified auto tech and I still have to tinker to get one right. That being said mech secondarys have there place to, they are easer to set up and they will respond slightly quicker, by the way quicker does not always mean faster. And if you use this car has a dd then you need to weight the slight preformance gain with the rising cost of gas.
I guess what I am trying to say is there is no right and wrong choice I am just trying to give you a little insight from what I have seen over the years.
The more you tinker on the diffrent carbs the better you will get a tuning them, and that is the best way to learn how.
What ever you chose good luck.

I will post a review on the new summit carb after I get a chance to get the car to the strip and run some passes with this carb vs my Holley. I will also be checking to see how hard rejeting is as will as secondary adjustment with the stock unit. I have a quick fuel secondary unit for it but have not installed it yet. But bottom line I paid 236.00 dollars for the carb brand new and that is a great price on a new carb with electric choke that worked pretty well right out of the box.
But that being said if it were not for the price it would have not been my first choice.

There is nothing inherently better about vacuum secondaries over double pumper for fuel economy. You are running on the primaries on either one for "regular" driving.

Regardless of how well you get it tuned, a vacuum secondary carb is not a good choice in a T5 car.

I am new member here and dont want to make any waves, he asked for a carb he could use that would cost less than 400 dollars. I am just trying to say in that price range that was a choice, not that it is the best carb for his car, but for his budget.

As for the argument of vac over mech secondarys, we could debate the pro's and con's forever. But I am new here and will defer to the moderator.

yea that would be a good choice tomcat, nobody wants to beside tracked from the op's question with debating, lol.

for the op, five 7 has you pointed in the right direction, with your engine i wouldnt rec any bigger then the 750. and obviously u will want mech secondarys. a 650 would get you out of the hole a lil better, but 6500rpm shift points, i would stick with the 750. and the 373 will compensate pretty good for the low end loss of a larger carb anyways. for a $400 budget, i would look for a good used carb, but keep in mind, you will most likley have to go thru it, cause people dont always give you the whole 9 yards on whats been adjusted and jet sizes ect. holley has trick kits for the 4150 at about $35 and they have everything you need to rebuild a good carb. good luck and happy tinkering. its to bad you dont need an 850, i have one sitting around i wouldnt mind getting rid of to help pay for my e85 conversion.

Yay IROC 86 I have been saving up to get me a quick fuel E-85 carb for my 383. If you get one before I get one how about let me know how it does. I am wondering about the power and driveability as well as if it will help keep the engine temp down. I know in the drag car we switched over to alcohol years ago. It runs cooler, and now days costs a ton less.

I will try and do my profile this evening, I will post pic's of my cars as well as some of my current prodjects.

This is my first third gen T/A, I have a first, second, and now a third. I will try to post pic's of each.

I know I am off topic here so I will end with this. I have noticed most of the members here are from out west, do you have many members in the south east?

yea, i looked into the quik fuel, but im goin with a custom built unit tailored to my engine/car. im gonna mail him my methanol carb and 400 bones, the guys at planet e 85 refered me to him. after talking to him, he knows his shlt. he said the quik fuel kits dont mention the modified boosters and the 4 corner idleing circuits. i donno about the quik fuel completes tho. with any carb outta the box there will be some adjusting. anyways if you have a carb already thats sutible in size, he will set you up. if your interested i can tell you how it runs in a few weeks, as he is only about 1 1/2 hrs away from here.
