Timing

I have a 81 z28 with a 350 bored .030 over with an Edelbrock Torquer Plus cam and Torquer 2 manifold. I can't seem to find my information on my camshaft, etc to set the timing correctly. When I start out from a stop sign if I don't put my foot in it a lil bit, the engine kinda sputters out and stalls a bit before taking off. I've checked the fuel system as best I can, changed the spark plugs, and adjusted the timing to what I think it's supposed to be (or closer to it), but the problem persists. If anyone has the timing specs for this type of setup it would be a big help, and any other ideas or suggestions would be also.
