zz4 or 330 hp vortec

[socor7]

Just getting some opnions and pros and cons. I am thinking of getting a zz4 short block and using my existing cam and heads and build up a motor, or buying a gm 330 hp vortec head long block. I have S/R heads from world products with 67 cc chambers which would give the zz4 about a 9.5-1 cr and this is the cam that I have

I also have a edelbrock performer intake with a 600 cfm carter afb carb. I am not afraid of the build up, but have never done it before.

Thanks for you info.
