cam choice is dependant on your goals and wants.
I am sure an aftermarket cam will make more power and be more radical so say.
But if you want a very mild setup with stock like features run a stock came such as the ls6 or ls9
ITs all in what you want out of your setup.

 

Can anyone confirm if the timing chain dampener is required for the LQ4 when using this cam. Is there holes in the LQ4 block to mount this piece.

Thanks
