I have 3 intakes to choose from:
Weiand Stealth (gasket matched, plenum divider cut down)

Edelbrock 340 Torker II (no mods)

Edelbrock 340 Victor (no mods)
Which would be my best bet for what I have?
 
I am not a big fan of the Torker or Torker II on a small block Mopar, and that is from experience.
 
On the street my W2 head 408, 4 speed, 3.23 geared Dart will vaporize the tires at any speed in first or second gear with the Victor W2 on it. On street tires 3rd gear rubber is normal. No loss in low speed torque with the stroker, traction is the limiting factor. Cam is 237-241, .580 lift, 106 lsa.

Your automatic, mid stall convertor, and 3.91's will be into the torque fast enough anyway. It is my opinion, anything but a good single plain will hold you back.

If I recall from another thread you said that this was street/strip, but more street correct?

Any which way, I would use the Victor from those 3 intakes....however, better suited for that combo would be the Air-gap (looking at your heads/cam/converter choice) for better low end performance....Also, with that said, you probably won't notice the slight bit of low torque loss using the Victor...the 408's are torquey little dudes.

For what its worth, I have use both the Victor and the Air-gap on a similar combo (410, ported Eddys, 10.8:1, 248/254 cam, ~530hp) and the Air-gap could hang pretty well, but the Victor always made more HP up top (more MPH through the traps on the 1/4 mile). Best on the Air-gap was 10.89 and the Vic was about a tenth quicker (going apples to apples).

Edit: I forgot to mention, I was using an 8" converter (5k stall).
 
in the market for another converter. I'd like to go with around a 3500 stall for future upgrades. What do you guys recommend?
 
With that cam etc and intended use a Turbo Action 17805ST 3500 tight will deliver without having to resort to a “custom” It’s a great converter for the street and strip. You have plenty of options though, could go higher on stall but I’d call around and get recommendations. You’d be surprised on how high a flash stall you could run yet still retain excellent street manners.
 
How do the Holley Strip Dominator and mopar M1 single plane small block intakes compare to the Victor?
The Holley was made first and also sold through direct connection back in the day until Ma’MoPar started to make there own stuff and copied and improved the Holley. The Edelbrock performs at a higher rpm and is a little better up there.

A similar build, 10-1 IIRC, rpm intake and a 750...
And Trick Flow heads. Compare flow rates up to the valve lift of your engine against the cam here and your heads flow rates for an idea of where you might be.

Check it n the kevco pan whether the oil drain is inside the swinging door sump area or out. Mine was out and it would leave a quart of oil in it when I would change the oil. The gates don’t let the oil back out of the sump to get to the drain hole. Simple to just add another drain in the sump.
