67 Belvedere
440 Ross 11.5 to 1, stock rods and crank, .590 cam, Edelbrock RPM's (with a little bit of work), Harland Sharp 1.5's, Weiand Team G, Holley 1000 HP, TTI headers with 3" Dynomax Ultra Flows, Reverse manual 727, 9.5" Converter 4500 stall, 8.75 with 4.30's, 29x9 Hoosiers

Here's my current setup. I wanted to see if its worth going to Victor 440. Best Et so far after only 23 runs 10.96@122

the mopar 337 is better and you dont have to use the stupid valley pan anymore

446 12.5 613/276 stage 4 heads ported ........ 10.85 123 mph

my M1 to the VICTOR 440 , with a 1050 , where about the same , both ported too and I was spinnining it at 6500

it would depend on the weiand you have now


what,s the weigth of the car

Sam, I've got both a 440 victor and an M-1 if you want to try them.

I'd bet so...

some light reading

It can be hard to beat a ported SD on the street on a high compression 440 or a 600hp 500 incher. A shorter runner will be less restrictive to the valve than a longer one of the same cross section, so unless you need more torque below the torque peak a shorter runner is generally better for power. SG's table kind of bears that out from Steve Dulcich's article on an 11:1 max ported 915 headed 440. The M1 is also a very good manifold but it has taller but narrower runners and it's a bit more work to port.

I agree with Chip the SD and Perf RPM are very close, particularly on an Automatic B or E body 440 to about 550hp. The RPM will make a little more torque and the SD will make a little more power and the cross-over point is around 4000rpm...et's will be very close. A heavier/tigher stalled car will favor the RPM, a lighter or 4 speed car generally the SD. But a street 383 based B/E car will almost always favor the RPM, IMO.

The huge advantage of the SD is not 'outof the box'; it is relatively easy to port to flow over 310cfm which makes it a perfect choice for many/most 500" B/RB's with E-heads, especially when you need it to fit under the stock hood.

You are running a Team G and it's NOT a torque maker below 4000rpm but it makes very good top end power. I had a 550 horse 451 stroker in a 73 duster with 3.91's and a fairly tight 3500 stall Fairbanks, a warmed over SD woked the best in that motor, the Team G was too soft below 4500 and since it was a 90% street car I wanted to keep the stall tight. I also tried an M1 on this motor and it worked about the same as the SD but noticably better part throttle torque and no less power than the G. The G works best in Light cars with 4800-up stall and deep gears. I think on your motor the Victor would be an improvement and would probably work AS WELL on your particular combo than an SD...but not necessarily any better. And with a little porting the SD picks up about 40cfm (from 270 per runner to ~310) pretty easily, and that's more than enough flow to support ~630 hp.

My sons Dart when we compared the Holley Street Dominator to the performer RPM:

Holley SD - 11.59 @ 117
RPM - 11.55 @ 116

Very close as the RPM was much better in the first 1/8 and after that the SD comes on and pulls more mph.. 3550 lb Dart with a .030 over 400 and 3.91's. Ron

im sold on the SD!!!!!!!!!!

Thanks for all the replys. Glenn, I may take you up on the offer. I did fail to mention that I have the Team G with 4500 flange. I am using an adaptor for my 4150. I have a Street Dominator on my dads Satellite that I can pull off and try but I'm leaning toward a Victor. If I go with the Victor should go with the regular Victor with the 4150 flange or the Super Victor with 4500 and use my adaptor again? Also, should I do some porting or run it out of the box?

Go with the victor you won't be sorry

Just do it. Intakes aren't that expensive. And you're not gonna know how much you'll pick up until you try it. Some have had great experience with a team g some haven't. Its just gonna depend on what your combo likes.
