Are there any performance differences in these two intakes on a mild 440? I currently have an RPM on my motor and would like to go to the SD for added hood to air cleaner clearence. Anybody know how much shorter a SD is than a RPM?
Thanks,

The SD is probally one of the best intakes made for a BB.I believe its about 1 inch shorter.The one I had on my 440 fits under the hood on my kids 62 300.Rocky

I run the street dominator with a 1" spacer and it fits under the hood of my 63 with no problems. It fit fine even when I had the flat hood on it. And the street dominator works great. It has good low eng and top end. My 63 goes 3700 lbs and has hit a 1.57 best 60 which is repectable for a mid 11 car. My son has the RPM on the 400 in his Dart and he loves it also. We ran a street dominator on his 400 and compared the two intakes. He went 11.59 @ 117 with the SD and 11.55 @ 116 with the RPM. The RPM was a tad better down low but the SD had more mph. Very close. Here is the SD on my 440 in my 63. Ron

Is the Holley 300-14 the Street Dominator everyone is talking about that you can still buy new? For some reason I thought they were discontinued and you had to find a used one? 300-14 Street Dominator

.030 over 440 with stock bottom end and KB quench pistons that give me 10.0 comp with my 906 heads I ported. MP .557 cam and Comp dual valve springs. SD intake of course and a 850 DP. Hedman 1-3/4 headers and 3" pipes. 727 with Dynamic 9.5 converter and 4.30's with 30 x 9 tires. 11.49 @ 116 best but I am building a 493 stroker as we speak hoping to get in the 10's and still be a pump gas eng.

300-14 Street Dominator
IIRC, the Street Dominator for the RB is still being produced and the one for the B you have to find used.

Small plenum single planes work well on even mild engines. The big block SD is the best of them. An original advertisement for the Torker 440 claimed the "New" (1974 ad) Torker single plane manifold when bolted on to the emissions choked Dodge and Plymouth big blocks brought back some of that lost power. Then the add went on to say if you bolted the Torker to a 67-71 engine..."WOW!"
Keep old mopars alive.

Here is my build that I am calling mild:
• 71 440
• Stock rods and crank
• TRW Forged Flattops; approx. 10:1 Static Compression ratio
• Out of the box Edelbrock RPM heads (84cc)
• Stock style rocker gear
• Comp XE285HL Cam, comp lifters,
• RPM Intake
• 750 Speed Demon Carb
• MP Electronic Ignition
• Doug’s 2” Full Length Headers
• 3” Magnaflow bullet mufflers out the side like a AAR currently, coming a 2 ½ “ X-pipe exhaust system. Current system way too loud.
• 833 4-speed
• 8 ¾” rear 3.91 sure grip
• 275/60-15 rear tires (28” tall)
I may eventually change the cam to a bit smaller one to get better idle characteristics. Thinking on the Luntai 60303. Also may add a BIGS 850 DP or Proform 850 DP. Other than that, this is what I have. The RPM, because of height and stock hood, limits me on air cleaner space. If I would not be doing anything stupid to rob me of significant bottom end, then I would like to change to the SD.
Thanks,

I would put an SD on that combination in a heart beat. You will not be disappointed.

That combo will like the sd alot.The idle will be better with the dual plane but other than that the combo will respond well to the sd.Run plenty of initial advance and it will help the idle also.

That combo will run good on the street, especially with the 750 carb. If you want to make the most of the SD single plane, Eddy heads, and 2" headers however, which all will allow a 440 to breath north of 6k, you may want to think about a bigger carb. The 750 will likely start costing you power at around 4500 - 5000. But as said, it will likely run crisper around town than an 850 would.

I had a SD on a 72 440. Worked well. Put a RPM on it and it was much better. Little bigger carb than the Holley EFI I was running, 750 vs. 700. Had much better low end with the RPM. Running a SD on a low deck currently. I like it but can't help but wonder if that is why I seem to be down from previous MPG's from other 383s I have had with the stock intake on them.

....to me it doesn't look like enough difference to worry about at the 450hp level.
Dave
In the article you linked to , if you only look at the peaks, they seem similar. But look at the numbers at 3000 rpm: 381 ft-lbs for the SD, 408 for the RPM. In a car with a low stall converter,I would expect the RPM to have noticably better low end than the SD. Oops, I guess I should read all the posts, not just the last few. I don't think you can directly compare the B versions of those intakes to the RB versions. I have heard more than once that the RB SD is better than the B. I suspect that the RB version is a better low end torque producer due to the slightly longer runners . Anyway.... after reading the OPs combo, I would bet that on the strip, the SD and the RPM would probably E.T. very close to each other. On the street, when you don't feel like downshifting, the RPM may be a little more responsive.

First hand experience on my 71 Bee / Street car
#s 383 Mag / Balanced / .030 Over Forged / Old school Mopar 284-484 cam / 18 initial - 38 total / 3:91 Gears / Blah Blah
The 383 Holley Street Dominator off idle or launching at say 2500 rpms is a dog - That intake does not come alive until at least 3500/4000 Rpms and anything above that it flat out performs
However
The Edelbrock Performer RPM / Even just the Edelbrock Performer is just a much better intake on a mildly built 383 Mag Street Car
Like others have stated - On the 383s the Street Dominator just doesnt have the low end torque and it really shows in that Hot Rod Article and from my experience testing all three intakes on the street launching / off idle etc.

I tried both years ago, and found very little difference between the two on my old reringed '73 440. 12.60s with the SD, and 12.50s with the RPM, MPH was exactly the same between the two...the only time it would break 106MPH is when it had wheelspin. If it hooked up, it went 106 every time no matter what I did.
RPM felt perkier at small throttle openings when driving it easy. SD was also fine, but not quite as responsive to a light touch on the throttle. I had a 4 grand converter at the time, which should cover up any differences, but it was still noticeable.
I think I liked the rpm a little better on that combo but the difference was small, can't really go wrong with either one.

The graph info waspulled fron the following the Moparts Link: https://board.moparts.org/ubbthreads/show...e=1&fpart=1From: Dave Freiburger Date: 8/27/07 We have a winner: "I'll put the overall average TQ and Hp on the 6bbl, then the RPM, then the Torker." Here's what our test showed. Each test is an average of two dyno pulls to remove anomolies. The numbers shown represent average power from 2,500 to 6,000 rpm. However, even averages do not tell the entire story. For example, the Torker and the RPM have the same average numbers, but they are not the same: the power curves cross at 3,900 rpm, with the Torker making more high-end and the RPM making more low end. As for peak power, the Torker, Street Dominator, M1, and Victor were all at 455-456 hp at 5,900 rpm. Nearly every manifold made 450-460 lb-ft at 3,800-4,100 rpm. Most of the dual-planes were way stronger than most of the single planes at rpm points below peak torque. Duh. I think the tunnel ram would have done a lot better as a dual quad. I was surprised how well the Six Pack did, but I think that's because of this engine's low-rpm and low displacement. Six Packs have killed big power in other tests with other more radical engines. That just proves that you really have to consider the test before you can make a judgment call, and you can't just look at one point of data and say "that's best" overall. It will also be interesting to see how this may change when we put better heads on the engine. If the 906 heads are currently the restriction, then other weak points in the intakes will be revealed with better heads. More data in the December issue of HRM. 2500-6000 AVG 3000 4000 6000 INTAKE LB-FT HP LB-FT HP LB-FT HP LB-FT HP Six Pack 428 348 413 236 459 350 391 447 Torker 427 348 395 225 455 356 397 454 Perf RPM 425 346 408 233 457 348 392 448 Victor 383 425 346 M1 single 424 345 1x4 tr 425 346 TM6 424 345 DP4B 424 344 419 239 454 346 387 442 Performer 422 341 418 238 452 344 382 436 Action Plus 421 341 Street Dom 421 344 381 217 449 342 395 452 Team G 409 334 Offy 360 406 338 Offy 2x4 408 330 Offy DP 404 327 Here are just a few data points. Also, a reminder that this thing had STOCK heads. I think the heads were the restriction, therefore the manifolds did not make drastic changes; except for the really bad ones, the different intakes just wiggled the numbers around by 5-10 hp or shifted them to the low rpm (dual plane) or high rpm (single plane). I'm pretty certain there will be more difference between the intakes once some better heads are on the engine. I find that out at the end of the month.

That's a great article, but I hadn't seen the graph results before: thanks! It's sure nice to note that the 6 pack did so well, especially since it's the only stock manifold in the test. 450ish hp is a great comparison point as it's right where alot of enthusiasts are, power wise. I'd note that there was a follow up to this test at a higher hp level for those interested. Dave

At the 4K point it shows the Torker as having less torque but more horsepower than the sixpack or the rpm. Looking at the formula for HP
(Torque x RPM) / 5,252 = Horsepower
you can see that at any fixed rpm if the torque is higher the HP must be higher also. Oh well not the first time a magazine goofed.
In theory, there is no difference between theory and practice. In practice, there is.

what torque converter are you running? i ran the same combo for 10 years, that cam in the 383 has more to do with it being a dog below 2500 rpm than the intake does. the more gear and converter i pit in mine the faster it went, however i started out with a dp4b intake, then tried a torker, then a tm6 and the last intake i tried was the performer rpm.

Ok so we have the numbers now.. Can I run my stock kickdown and throttle cable with a Performer RPM intake.I have a Weiand now and can't find the right setup.The car is a 71 Superbee 383 column auto.Any HELP would be appreciative.
I think the reason that Andyf started making the taller throttle cable brackets was because of the height of the Performer RPM intake.
You can get his brackets from several online venders.
You will find what you need about 3/4 of the way down this page.

Thanks so I guess I will have to get the 3 or 4pcs. kickdown to make it work.
