I have a 2000ss. right now i dyno 372 rwhp. I have long tube, lid, fast 78/78 setup, 220-224 .581 114. cam and a cut out.i still have stock y-pipe. So, recently i have purchased a smooth below, SLP 85mm MAF (de-screened), 3" y-pipe and a 231/237 .595/.595 112+2 cam. these havnt been installed yet. What kind of Rwhp you think i can expect? thanx
