Single plane on a street car??

-
Yep. That magazine tests are worthless. Go to Comp and look at the lobes they are using. Even they say it isn't a street lobe. It's also on a 108.

A better cam choice would have made the SD the better choice.

The test, despite the cam, answered the OP's questions was my point.
 
Strip Dominator was tested, not a Street Dominator. RDA asked about the latter.

As far as the LD4B abd LD340 go, there are four pages of excellent discussion on those.
Edelbrock LD4B
 
I have a Holley street Dominator intake manifold that is a single plane (not sure if they all are)

I am not really familiar with aftermarket intakes as I have only run factory parts.

Is this a good manifold to use a street driven car?? The combo is a 340/4speed. the 340 is a 73 and mostly stock and is a good running original out of a 73 roadrunner.

The car it is going in is a 71 scamp
I've run that intake and its decent. Ran good at the track and autocross. Idle to off idle was OK for street. As good as stock with a stock cam? That I can't say. For hood clearance its great. I ran it with a 4 hole 1/2 phelonic spacer. I'd suggest an insulating spacer like that. Might also want a valley oil spash pan to keep the hot oil off the bottom. For the throttle cable, a low rise bracket is needed. I think I took mine from a 2 bbl in a wrecking yard.
I wouldn't worry too much about the smaller port disparity. It has advantages - I should have left mine that way for what I was doing. Mine was port matched. Do this carefully if you do it as head port to bolt placements vary from head to head.
 
I have a pretty hefty built w2 340 stroker (418)
I ran the single plane m1 w2 intake on this bad boy. She loved to scream up top but felt weak down low unless I dumped the clutch at 3 grand (give or take)
I then switched to a w2 dual plane and OH MY GAWD The torque would grab your throat and stuff it into your rectum..

For your place a dual plane or the Eddie air gap intake. Especially if street driven. Single planes can work on the street but revving at 3 grand at the stop light is no fun.

I am no expert either
Was this the M1 dual plane w2 intake, or a modified LA intake? I'd love to hear about your engine specs, I'm going to try one of the dual plane M1 intakes on my 408 W2 engine.
 
Holley Street Dominator is fine for the street. In a big block it is pretty darn close to the Edelbrock RPM dual plane intake.
 
@72bluNblu nailed the answer = @Rainy Day Auto it'll work on a street car for sure it really depends on how you plan to drive it and what is important to you performance wise. you'll suffer a little on bottom end torque but overall it should do you well.... any other performance mods going with it?
 
4sp can cheat on the powerband by keeping everything higher. Only reason Mopar went with a single plane on the new for 65 4bbl was the height limitation of the existing platform. Dont know why they didn't choose a dual plane and make the air cleaner a drop base? Probably cheaper just to add a 4bbl pad on the existing 2bbl intake. They said they did 'extensive testing' (with accounting???) on the new 4bbl single plane intake for the 4bbl package but who knows...
 
I've run a lot of manifolds on my 340 Dart over 25 years - for the street I'll always take an LD340... Weiand Stealth is a close second.

I ran an X-cellerator single on a stock low-C 318. It worked pretty good; with TTI headers, twin 3" duals, a Commando box, and 4.30s.. A smallport cast iron and TQ worked better with a 904/3.55s
I ran my HO367 with a factory iron intake and a TQ. Also with the the X-cellerator on it. But the AirGap covered both ends better.
If I already had the Holley installed, I would run it; but on a low-C 340,I would not swap out the factory iron for it.
I think, when it comes to intakes, and on the street; the rest of the combo has a lot to do with it, especially when ~90% of driving is below 3500, and mostly at part throttle. Here torque is king. With a low-C engine and 3.55s, I'd sacrifice 20hp at 5000 for 20 ftlbs at stall.

I have run single planes on every hot rod I `ve built , and had no problems with any of them , that being said , all have had a lot of torque and h.p. , the single plane wraps fast and has shown me no loss of low end power when tuned right.----jmo
If its a street only small block ???????????

If you are running a stock 73 340, just run the stock intake and Carb. They run great on the street. The Street Dominator is for small port 273/318 heads and will be a power loss.
 
I’ve ran a few street dominators. I really like them. The Z series is the best down low on account of the plenum divider and balance tube. Kim

Dangest thing I ever saw, musta been a rea low flow on either 1 or 2 . ??
It is different that’s for sure. It’s a balance tube between cylinders to equalize the cylinders. Back then because of the firing order it was that number 5 would be robbing fuel from number 7 on the left bank and I believe 8 and 4 on the right bank. Google Zoe’s Arkus Duntov. He is the father of the Coevette. It is his design. Kim
 
Yes, it will. Kim
Thanks man. I haven’t had that particular model in my hands, so I didn’t know for sure. Some companies have cast a spreadbore pad but not large enough for a TQ carb. @high.rev.trev just picked one up for dirt cheap. He just posted a picture of the bottom. IDK what the top side looks like. A few of us are awaiting pictures. The one I had was good to go for a TQ with a very wide open area.
 
Well, I’ll just have to try a TQ on it, I just figured because it had a spread bore pattern it would fit, maybe it’s for the Rochester Q jet cause this style was made for the Corvette. Kim

Yes. A Thermoquad will fit ..
If a Q-jet fits, the Thermo will.
Heresafew pics of another Street Dom too, this one the"Z" Version, like other pics...
Mmm
