Comp cams Quest

Has anyone used the comp cams program that they have on their website called Cam Quest? If so how good/actuate do you think it is? Im looking into doing a cam swap on my 383 in hopes of getting a lot more lower end torque but still maintaining a nice power curve.
Current specs-
383cu
Canfield 220cc heads
12.8:1 compression
Edelbrock victor jr intake
proform 750 race carb(wanna prob go bigger)
Cam- not sure of the exact specs but the guy said its a howards solid roller with .645 lift. he didnt know anything else.

Does anyone have any good cam recommendations? im looking for a lot of low end torque but a nice power band.

Thanks
Matt
