best intake for torque.
Now that I have my engine out I was able to get a good look at the intake, it’s an Elderbrock Street Dominator.
I’m wanting something that will give me the most benefit in the low to mid range, mainly torque. What seems to work with the Quadra jet Carbs? s/t

Re: best intake for torque.
I've built 38 different small block if you can try to match everything cam heads intake carb to get the best benifit. but if you can't go that far maybe just cam and intake. but any way a real good choice is the edlelbrock air gar
edl-7501 or polised edl-75011 you street domiator is ok also but isn't it made by holley Last edited by RACINJASON22; 01-22-2007 at 11:11 PM. Reason: forgot to say |

Re: best intake for torque.
just remember a quadrajet is a spreadbore flange...
if you buy a new one get one that mounts with the carb you plan to run. edelbrock and holley are squrebore flange.. |

Re: best intake for torque.
Is not a dual plane, it just opens up straight in.

Re: best intake for torque.
If you are building a low end torque engine you can't beat a stock iron manifold. Of the tests that I have seen between the stock manifold and various after market street dual planes the stocker held it's own and in some cases posted higher torque numbers up to about the 3500-4000 rpm range. Hot Rod Magazine did a test a few years ago between the stocker, Performer and Performer RPM. All 3 were virtually a dead heat up to 3500 then the stocker fell off a little in the mid range. Of course the Edelbrocks posted better HP numbers in the upper mid to top end range. Installed with a Q-Jet on a torque engine that would rarely see the top side of 4500 you would get very good results with a stocker. GM made some aluminum versions in the '80s that take a Q-Jet too if you want the look of aluminum. I have one out in the shop if you would like to see what it looks like. I put on an Offenhauser I also had since I'm using a stronger cam and ported heads and decided not to use it.

Re: best intake for torque.
what about the Offenhauser dual port 360? I thought some one here had one.
another one that I had exceptional results from is the Stealth from Weiand. and it was about $5 cheaper than Edelbrock's performer. Last edited by 68C15; 01-22-2007 at 11:44 PM. Reason: coco puffs taste great at bed time |

Re: best intake for torque.
Ok my bad, I was thinking of the holley street dominator- Its a dual plane. I think a dual plain is your best bet. just my .02. Good luck with your build!

Re: best intake for torque.
If you are thinking about up grading later on check out some of the pre-made kits available from holly edelbrock you pick then go with the intake frome that kit you will spend a little more in the long run by not buying in a package but I for one know how hard it is to come up with all of the money at once. Later when money allows you can buy the other pieces of the package.
by the way that part# is edl-2601 spread bore and square flange so you can even upgrade carb a a later time |

Re: best intake for torque.
I used the Offenhauser 360 on my 355 with a square bore Holley but it isn't the Dual Port. The catalog claims good off idle to 6000 . That seems rather optimistic but Weiand claims the same for it's Stealth. We will see next summer.

Re: best intake for torque.
I second the stock intake comment...
money would be better spent on cam, carb, or gears. rather than replace a perfectly fine stock quadrajet intake, with a $100.00 version with the same results. My thoughts are; to improve torque, change cams... to improve seat of the pants "feeling" of torque, change rearend gears... My .02 cents...

Re: best intake for torque.
There are lots a good intakes out there for torque as mentioned above. I personally have had very good luck with the edelbrock performer on small blocks and Weiand Stealth on Big blocks. Don't put on too large of a carb. and you'll have great torque and good throttle response. Just my .02

Re: best intake for torque.
Maybe I should just keep the Eld. Street Dominator? Does anyone know how it should perform? It sounds like the performer duel plane will give me torque & mid to hi RPMs. I’ve also been looking at the holly fuel injected units as a package deal. They look good. I wonder if you can data log with those units to tune on the fly using an o2 sensor?

Re: best intake for torque.

INTAKE LINK you can mount any carb squrebore or spreadbore and not be limited to one carb..0-5000 rpm range TO INSTALL A SQUREBORE..just use pictured plate Last edited by rage'nrat638; 07-12-2007 at 06:58 AM. |

Re: best intake for torque.
I would say performer intake for sure with a mild cam and a small vac secondary carb (600-650 size). If money is an issue then the dual plane stock intake, it is easier to change out later on too if you want to go the aluminum route.
I think they make a performer rpm intake spread bore version just not in the air gap type. |

Re: best intake for torque.
Right on rage'nrat. The air gap # is EDL-2601 in square/spreadbore duel patternhttp://store.summitracing.com/partde...5&autoview=sku
Claimes Idle to 5500 very responsive. Plus the air gap keeps the carb cooler plus I love the way they look Single plane look Dual plane power!!! |

Re: best intake for torque.
Does this count as an 'intake'?

Re: best intake for torque.
No problems that I have heard of, but the reason for it is to keep the carb cooler for more power, denser air fuel mixture. I never really thought about it.
