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.

I would put an SD on that combination in a heart beat. You will not be disappointed.
In theory, there is no difference between theory and practice. In practice, there is.

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.
