I have a 1973 plymouth duster with a 360. It has an edelbrock torker 340 intake manifold on it and a holley 4-barrel 650 cfm double pumper. Is this any good? Should i try to replace the manifold?

The Torker is a single plane manifold and it probably works well in a higher rpm setting depending on your cam and they way your motor is built. Like the guys said, the performer rpm is the best for most applications. That's a good manifold though.
 
What's the rest of the combo? Compression, cam, exhaust type, transmission type, converter stall, gear ratio......before we say anything sucks, lets get some more info.
 

It's a high RPM designed intake. A dualplane works better 90% of the time, but there is always that 10%.

Here goes, you asked!!!

The torker 340 is probably the worst intake edlebrock ever produced for a SB mopar. They should have smelted them back down and made anything else out of them. Not a good intake at all and works in a VERY limited performance window.

An air gap, Performer RPM, LD340, LD4b will be a HUGE step up in performance
 
Holley Street Dominator was decent for a mid range intake if you need or want to stick with a single plane.
With the 360, try it with a 1/2" spacer or taller. Depending on the rpm of interest, may want to match the port, esp the roof, to the heads.
 
The 650DP is probably saving your combo.
As would high compression,a small cam, a higher than stock TC, and bigger rear gears; be saving your combo.
If you're happy with the current performance, depending on the rest of the combo, swapping it out could make a huge difference or next to none; it's all about the combo.

When talking combo, these are the high points;
intended useage
engine size
heads or headflo
cam type,specs,installed center-line,
Compression ratio/cylinder pressure
headers or logs
fresh-air intake
intake/carb
exhaust system
trans/stall/ gears/weight
The parts you choose and how you assemble them, can make or break your combo
