Generation IV External Engine - what hp is an ls3 intake good to? will it work on a 408 with cnc ls3 heads?

Im doing a build on 408 with tsp prc cnc ls3 heads and a pat g cam. I already have a stock ls3 intake im just wondering how much hp im leaving on the table with the ls3 intake. I know of a few people with 5th gen camaros that have swapped from their ls3 intakes to fast 102 setups and only picked up like 3-5 hp so im not looking to waste money on a fast set up just yet.

You can make 500 RWHP with them. The bigger the engine the earlier the power will peak. The 102 needs to be port matched and the runners ported to show the bigger gains. IMOP. The T-body also needs to be a 102.

I'm going to go with a Mamo ported one after much discussion and research. I think it is the best choice for a street driven car. It will be the easiest to install by far.
