I have a 2004 Mustang Mach 1. I recently blew up the motor so it’s currently equipped with a livernois motor sports iron block with all forged internals. My other mods include, an intercooled vortech supercharger system, bbk long tube headers with a bbk catted x pipe and a magnaflow magnapack cat back, a steeda tri ax shifter, accufab throttle body, spec stage 3 clutch, and 4:10 rear gears. This was all tuned using a sct xcal 2 flash tuner. This combo made 470rwhp but after it blew up, i had the new motor de-tuned to 441rwhp.
