Can anyone compair these cams for me due to either personal experience or Numbers or anything im not sure what cam i want so i wanna take a look at what might be the best for me

Cams:
CC306 and
GM 847

WHat i plan on doing:
Possible 355 with forged pistons stock rods stock crank (mabey do rods depending on the money)
Ported LT1 heads and a cam.
current mods are below and i dont wanna really rev WAY past 6k i relize the powerband especally for the 306 is past 6k but id rather not be up that high.

im also complelty open to other cam options im not partial to anything

thanks in advance
