Would it hurt to put a mild cam in with the stock rebuild?

I think that cam would be a great street cam option. It has some valve lift with streetable duration. Your engine will want to pull out to about 5500 which is a good stopping point for a light performance 289/302. Edelbrock heads will work nicely with that. Just make sure you match your intake runner and combustion chamber size to your cubic engine displacement. Too much intake runner volume will hurt your performance. Too little combustion chamber will run your compression ratio up beyond pump gas.

Hey Nick,
Have you thought about the Retro-Fit Hydraulic Roller cams from Comp Cams? These would really improve performance, help with the MPG a bit and allow your compression ratio to be a bit lower. I did a lot of reading last fall and made a number of calls to the manufactures and here is my 351w daily driver build..
COMP Cams Xtreme Energy Retro-Fit Cam and Lifter Kit (CL35-421-8)
COMP Cams Retro Fit Hydraulic Roller Lifter Kits (CCA-31-1000)
Edelbrock Performer RPM Cylinder Heads (EDL-602519)
Edelbrock Performer RPM Intake Manifolds (EDL-71811)
Edelbrock 650 cfm Thunder Series AVS Carburetors (EDL-1806)
Keith Black Hypereutectic Pistons (KB303-030-8)
You might want to really think about the Comp Cams CL35-421 roller cam upgrade. The CCA-31-1000 kit requires 2 holes being drilled in the upper valley of the block to help keep the lifters aligned. Do this yourself or have the shop do it. The heads and intake I got are polished so they cost a bit more but hey.. thats what she wanted. For a street car the 650 cfm Thunder carb will do great and there is no reason to go any higher.
I called Keith Black Performance Pistons (Owned by United Engine) @ I believe 1-800-648-7970 and after a few questions they were able to tell me exactly what pistons I needed. The KB303 series (bored .030 over and a set of 8) will give me a compression ratio of about 9.3:1 with the parts listed above.
If you have any questions feel free to ask me. Since this is my first engine build I understand how lost you can feel.
