All a "go-no-go" test does is check to see if the venturi is stock. Many other things can be done to the 4412. Replacement base plates that measure 1 3/4", along with ported main body and a custom tailored racing metering block. Also "modified" boosters help to improve fuel atomization, signal strength and mixture distribution. These modifications can make a 500 cfm 4412 flow up to 600 cfm.

I don't know about carburetors but I do no that the go-no go only checks the outside. What is inside makes a lot of difference. How do you know what is legal? One that costs more money or what. We have a rebuilt one I bought for $75 and had it rebuilt by Terry Henry's dad. Should I be looking for something better? Is a Willy's better and still legal? Larry knows a lot more than I do and is still asking what's better. Get the info and let me know. Wally

Old School, I have to disagree with you somewhat. It depends on the track and the tools available to the track. At some tracks they will check not only the Venturis, but also the fuel boosters for opening size and height, the base plate and also the throttle/butterfly shaft size.

We had a Competition Carb out of Sparks and then got a gauge legal Willy's and the Willy's was so much better. You could see results from a jet size change and the car was way more driveable...IMO

Perry25 -- my post was basically a answer to this question ----

I agree with you, there are many more things that can be teched if the track rules say stock "no touch" 4412"s. The E/W rule "was" just that, and when I teched their carbs I did not use a go-no-go gage, I used a pair of inside calipers becuase there are ways of making the venturi pass a go-no-go gage, (oval venturi), I also checked the boosters for size, and I had the guys remove the carb so I could tech the base plate for size, also the throttle shaft and butterflies for any machining. Thats as far as I went becuase I figured those were the main places where performance could be picked up .................

VDL carbs are ok but there is better out there its everyones own job to try and gain the most power and try different things unlike Bakersfield one person did good with one carb and everyone runs and gets the same one!!!!!

Racers are monkeys - monkey see, monkey do. If the guy who keeps beating you is running a VDL, then you must get a VDL to run with him. Goes for suspension setup too.

Nothing is better than a VDL 2bbl period. It feels like a 4bbl. I've tried everything from Blake, Carb shop etc and VDL whoops on all. Once they are ok in a class, you need to have one or you better find some extra HP somewhere else to make up for it. Almost impossible to police the metering block. I've read some tracks swap the metering blocks in a no touch class but that would suck if you invested 6 large in a VDL carb.

The VDL owner (dan, I think) is awsome, he will talk to you even when he is at the races.

We took a motor to the Carb Shop in Ontario to dyno.
It had a brand New VDL 4-bbl on it.

we broke it in and made a few pulls and the carb shop guy said, I wouldnt change a thing, that carb is dead on.

we have dyno'd 2 other different VDL's (2 and 4-bbl) here in Ridgecrest and they both were also dead on as well.

I have a $1000 Biggs 620 4412, and we would rather run the gauge legal VDL any time
