Just FYI, was watching Speed channel the other day and they did basic intake/exhaust mods on an Impala SS LT1, then ran dyno after each mod. I realize this is an LT1, but just to give some idea of the gains.
Base RWHP 210
SLP CAI 218
Holley Avenger Throttle Body 220 RWHP, but really extended the peak range. Added about 12 hp at high end where it had fallen off after peak before.
Flowmaster American Thunder 228hp.
