Hello all,
I race a dirt 3/8 mile high bank track in eastern New Mexico. Just after the end of our season, Sunday, our track manager let me know that next year we will be going strictly to two barrel carbs. I know plenty of other tracks have two barrel restrictions, so there should be pleny of people around with experience at what works.
From the looking around that I've done, it looks like the Holley 4412ct is the easy, popular choice. Does anyone have a better option at a reasonable price? I've found the Holley for under $300 and I can live with that. I don't know if there is a great two barrel intake that will be perfect for the carb or is a four barrel intake with an adapter the best route to go?
Like I said, its a high bank 3/8 mile track. I'm running an old super stock class car. 2650 lbs with driver, turning 4500 RPM at the end of the straight. Mild but strong 350 with a th350. Trying to keep good strong torque so I can keep RPM low and don't have to chage motors like underwear.
Any advice is appreciated. Thanks!
Doc

hands down, the best intake would be the GM Bowtie Highrise 4bbl. Most any 4bbl intake would be better than the best 2bbl intake.
If you can run aftermarket aluminum, choose a Edelbrock Victor 4bbl. |

Thanks for the info.
There are no rules about intake, so I can run whatever I want as long as I'm running a two barrel carb.
Not to disagree with you, but the Victor series (according to Edelbrock's site) starts making power at 3500 RPM. I am trying to keep my RPM BELOW 5000. I have seen dyno comparisons showing the Victor doesn't make torque down low compaired to your average dual plane intake.
Am I missing something or is there just more to the victor that I don't know about.

The Edelbrock EDL 7501 would be a good choice.

If you are only turning 4500 RPM then it really wont matter what setup you go with, just use any open plenum 4bbl intake with an adapter to your 4412. If there is no rule on intake, what are the rules about the carb? You can spend a few bucks on an outlaw 4412 that will flow over 650CFM, but like I said, If you are only turning 4500 then it wont matter, you will just be putting around in the back having fun. The top guys will turn 7-8K RPM and run a Super Victor with a VDL or Willys prepped 4412 and come by you like your standing still. Just my .02

Dave, I appreciate your reply and respect your opinion and knowledge. Based on your experience it is apparent you know what your talking about. However, if you knew a little more about our track and how small of an operation we have, you might give me just a little more of a chance. We just had our last race of the year on Sunday. There were 13 cars...TOTAL. Thats the most we've had all year. Our car count is so low we don't even have different classes. Basically, if you have a safe dirt car, you can run it (no modifieds, late models or sprints, of course). We had a couple old bombers, a couple street stocks, one old mini that they put a bigger motor in and a few old "super stock" class, which from my understanding, is now a defunct class. My low RPM motor is very competitive with what runs out there. Yes, there are some much bigger faster motors, but most of them have cooling problems and I've beat them before with my old 305 bomber caprice because they weren't able to stay on the track the entire race. You can find our track here: www.facebook.com/HighplainsMotorSpeedwayClovisNM With all that being said, I was hoping to learn what others have found works for them. Its looking like a 4412ct with a performer (possibly air gap) and an adapter plate is going to be the setup I am looking for. Thanks to all who replied, I thank you for your time and knowledge. Doc |

Doc,
Wasnt my intention to offend you. Im not like that. If you are competitive with what you run then that is all that matters. You are obviously going to need all the torque you can get with the low RPM, so an open plenum manifold would probably hurt you more than help. Your in uncharted territory for me, as Im always trying to wind it tighter and harder. I would think your spacer should be a 2 hole type not an open oval, you will need to keep the velocity spreed up as much as you can. Best of luck!
Dave

Dave, I wasn't offended, I just thought you were more used to working with more big time operations with stiffer competition than what we have going around here. I'm from south Florida and racing is so much bigger and more supported there than here. Fifteen years ago when this track opened we ran 4 classes every week and had all weekend long events on holidays. Heck, we'd get 45 or 50 street stocks in one night sometimes, now we're lucky to get 10 total cars once a month.
Again, thanks a bunch for taking the time to offer your experience.
I've seen the open adapters, but didn't know they made one with two holes. I'll look for it.
Thanks!
Doc

Sorry, I missed the part about the 4500 rpm.
Just FWIW, you should be able to spin even a mild 350 up to 6000 without having any issues...but that's your business...

I race in Louisiana. I use the TCC (totalcustomcarbs.com) with the 2bbl Victor Jr intake. They ran it through the dyno and with their carb which is a 4412 fixed up they get 15-20more Hp than with my 4bbl victor jr. I have nothing fancy, like you, and I turn it 6500-7000 every race. Like "startnonthetail" said 6000 rpm will not be a problem. So get some bigger gears and go to the front! |

I would check with the track and make sure that a 4bbl intake will be legal. The street stock rules in Las Cruces and Tularosa (Alamogordo) require a 2bbl intake with a 6600 RPM rev limiter. Might want to go that route incase you decide to race some out of town races. I won a lot of races in Tularosa with a 313 intake and a 4412 without ever topping 6200 RPM. Where in Eastern NM are you?
