I am looking to get some opinions about the setup for my car. I have a 94Z with an M6. I just ordered some Jet Hot LT's today and I am picking up the Hooker Y-Pipe to go with them. I just made a deal with Lloyd Elliott to port a set of heads for me. The only part left is to pick out a camshaft. With the wide variety of cams on the market I would like to get some thoughts about what cam I should go with. I am currently leaning towards the Comp XE 227/233, .560/.569 camshaft. I like the specs on the cam and I think it would do well in a daily driver. My goal is to put 375hp or more to the rear wheels when I am done. Also, I currently have a Flowmaster muffler on my car, should I ditch it when I put my LT's and Y-pipe on? If so what muffler do you guys recommend? Thanks in advance.
Remember......I gotta get 375 to the rear wheels
