415 rwhp at 6800 rpm on a 348ci on a mustang dyno (stock 6.4 challenger with bolt ons did 402 on same dyno). With a baby 218/224 @ .050 cam.

Current fuel pump is walbro 460 lph in-tank
Previous fuel system was walbro gsl392 fed by accumulator and carter low pressure pump using a factory tank.
Both times I used a wix 33737 filter/regulator and deadheaded the fuel system
