Rupert, give Kevin a call at AGP he should be able to lead you in the right direction. I have a set of twin 57/57's on my stock (except for cam) LS3. I can't remember for sure but i believe he stated I could use those on a 416 build but they would cash out around 1000 rwhp. Might want to step it up a size or two and depending on your intentions ask Kevin about turbine size vs compressor size. Some go bigger on one side than the other and some run the same size on both sides. Unfortunately I am not smart enough to know the advantage of one over the other. Good luck.

My 57's at 8 psi are making 650/619 with a stage 2 BTR bump stick. I have heard that the bore to stroke ratio on a 408 is an awesome combo for FI.
