Technical carbs (speedway)

I know there's been some talk about the 9 super 7 carbs from speedway, is the consciences that there ok for the price. looks like the Goodguys gave them an award on new product. love to get some Stromberg's but the budget won't allow it. what do you guys think?? anyone have them??

 

how much are they? why not get an original and have someone like ****ster27 or uncle max rebuild it for you? i buy large logo 97 cores when i see them in the $100 range. another 175-200 bucks to have them professionally rebuilt and you're into them for about the same as a phony looking speedway carb.

 

Yeah or nicely done 94's which are way better too.

 

two carbs and offy intake 900 but will they work well or not? speedway says never had issues. this is why I ask some of the experts on here?

 

i've always used 94s--check ebay or swap meets--i think the last one i bought at a swap meet worked good and i paid about $60 for it. i just can't bring myself to pay the "new carb" prices. but rebuild kits are readily available, as is hardware, but, remember that if you run 2 or three of them you'll have to change the power valves for ones of lower value.

 

I bought the three carb set, built my own progressive linkage. I couldn't be happier.

 

For the price of some of these new carbs, ie: the Edelbrock 94, the new Strombergs, or even the speedway 97's, you can buy a nice 50 year old core on eBay, and kit it, and trick it out to the max and not hit near 400 bucks. Just my 2 cents. I've heard good things about the new 97's and negative things. Same with holleys and Strombergs. These old carbs are simple to work on, the manuals and rebuild kits are readily available and I think you'd be surprised how enjoyable it is doing it yourself. Especially if you're building a Tripower. [emoji16]

 

In that case, go right ahead.

 

I am running 6 Holley 94s. The number of carbs matters. Why? Because if the base leaks a little air on one carb ? No problemo. 2 carbs leak a little. Ok. If all 6 are leaking because the base is 60 years old. Problem. I went with 2 new 94's in the center and the 4 outers are originals that are rebuilt with new bases. Perfect. Ask me how long and how much money I wasted on old carbs to get here?

 

The speedways are designed to be less sensitive to too much fuel pressure according to the initial press releases.
If you can get good cores that haven.t been cannibalized, can clean and rebuild them yourself, you can be bucks ahead.
If you don't want to fiddle around and prefer driving instead of wrenching, new is a great option and is designed to be less finicky.

 

I've had a set of Speedways on my flathead for 4 yrs now and no trouble except this sorry gas we have to buy.Have to keep non 85 gas in it

 

Posted before, I've no opinion either way.

 

I know several people running Speedway 97s, with no issues, and they seem to tune just fine. At $300 for a primary and the same for a secondary, Not cheap for a multi carb set up!

 

As always, do a search on the HAMB for past threads. There have been many comments given on the Speedway carbs.

I can vouch for Uncle Max's rebuild work, and he also is a dealer for new real Strombergs as well. I don't know if he'd want to try to fix your 9super7's though.

 

Am I a minority here? I buy 97's off ebay, buy a kit and rebuild them myself. It is not that hard if I can do it. Why on the HAMB are we discussion buying new knock-off's or having someone else rebuild the for us. Sounds like a group of street rodders.

This!!
There isn't rocket science involved on 97's they are pretty basic things, just dive in, it takes a screwdriver and a couple wrenches

 

I usually don't pay more than $5 to $10 for a 94, or I get one from my buddies for free, cause it seems as if everyone around here has a stash of them.....I bought the (2) end bases from Vintage Speed and proceeded to rebuild/restore my own with a little help from Eastwood.

 

I was the same boat. I rebuilt a pair of old 97's and had them running on the car for about five years. I thought everything was done correctly, as it seemed to be running OK. Then one summer I had some hesitations and other maladies that made me think I didn't have them totally kosher. I sent the pair to Uncle Max for a look-see, and he found that when I first put them together I had switched parts from various carbs that were NOT COMPATIBLE. Who knew there were 97 parts that weren't supposed to go on another 97? Uncle Max did, that's who. Evidently there are quite a few varieties of those castings that have different size orifices not known to the normal hot rodder.

Plopped the re-rebuilt carbs (he subs***uted some parts for me, as well as a fresh cleaning and kit, and his magic finger adjustments) on the engine and it runs like a top. Thanks Uncle Max. I don't have enough hair to go through life pulling more out in frustration.

 

I know that the carb's that I have rebuilt are not as good as if I sent them off to be done. But for me, the satisfaction is in the little things. Over time I should get better at rebuilding them. Currently I have two motors with rebuilt carbs on them and they run well enough.

I don't want to take away from the expertise that Uncle Max has along with the others that do it professionally. I just get short on patience when the advice given is to pay someone to build them for you or grab your credit card and buy new ones. I vented the same the other day about putting chevy distributors into flatheads. Ten years ago I was told on the internet how to do the conversion, now I am told that I need to send it off to someone to build for me. Again, for me I takes away from the build and what this site is about.

Enough for me, the horse is sufficiently dead.

how do you clean the emulsion tubes if you do them yourself?

I love the Holley 94's on my 322 Nailhead.
