Default 408 with MS3 adding 200 shot? Keep it or go custom?

Don't know if this would be better here or the nitrous section. Keeping good power NA matters too so I posted here.

I am going to add a wet 200 direct port shot to my 408 in the near future but am debating about keeping the MS3 or not. I know they handle nitrous well with the 346 but am thinking that it should do well with the 408 also. I am plan on swapping to TFS 235 heads (have PRC 2.5 5.3s now) during the install.

As for the cam swap, I like the fact that a 240ish cam (114LSA) running warm is hard to pick up on the 408 through a muffler and going custom may ruin that. Anyone have any experience or seen anyone that has a similar setup/goals? Thanks,
Mike

Are you looking for a cam that reacts well to nitrous, hard to detect, and can still lay down some hate N/A? I would be interested to see what Kind of cam that Geoff@EPS or Patrick G would spec out for you for this application.

Exactly, I made 508whp/480wtq with the MS3/PRC combo as is. The TFS heads will net me a little more horse if I keep the MS3 but probably won't make much more torque since it will be topend from bottlenecking the PRCs. I'm liking the fact of a closer ratio on the hp/tq N/A. I just don't know if I should swap though. Currently the car cracks 400wtq around 2700 horse/torque cross over is at 5400 and horses peak at 6400 dropping at 66-6700. Plus the MS3 as of now is EXTREMELY Streetable which I am loving. Guess I am just torn between which would be more benefical

go custom, you should be able to sell yours for around $200 and get a custom one for around $400. Since you are getting it tuned anyways i think it is every bit worth it to have a cam ground for your application since it will only be $200 extra.
