I have a 00 Z/28 with a 402 stroker making 506rwhp 505ft lbs through a 60e and 10 bolt and like everyone I am always looking for a little more power . The car currently has a SLP lid with the 1313 ram air, a 85mm maf and a fast 92/92 combo on it. Has anyone seen any gains going to the 104mm FTP and 100mm Maf combo over the SLP and 85 or am I better off saving my money.
