Need cam selection help

[samikit]

82 silverado with an older 350 block. Its actually a 355. Truck runs good now but i have no idea what cam is in it. Was told it was a edelbrock rpm cam but it doesnt lope like it is. I want to know what i have in my engine so i want to swap it. This what i know about the engine and trans;

355 9.5-1 compression with 462 camel heads 3 angle valve job and porting.

Edelbrock 600cfm carb

Edelbrock performer intake. (I have a edelbrock high rise intake i could put on if needed)

Full length headers with 2 1/2 flowmasters

TH350 with shift kit 2500 stall.

342 rear gears.

This truck is my daily driver. I was looking at the voodoo 60103. Any good with this combo or too much? What do you guys think i should go with? Thanks
