    Would it be worth porting the TB and intake? Would I see any gains?

    Sure you would, better airflow, and better throttle response. I've done 4 of them now.

    Porting the Intake? Like the LIM? Probably wouldn't see much. And porting does give really that much of a horsepower gain...it is just for throttle response...it is when you UPGRADE TB's that you see a little HP gain, but still not much...I would be surprised if I saw 5 whp from my LS1. Reptile does a awesome job at porting and could probably hog out the lower intake too if you wanted him to do so...shoot him a PM He has done a lot of work for my car...and it is worth it
