Another update. Mocked up my hydroboost to see if I can get it to clear the coyote engine. Results look promising. Used a reproduction Boss 429 Mustang brake booster wedge to tilt the hydroboost up. Still need to figure out what to do about the billet hood hinge interference and determine what the brake pedal ratio needs to be. If anyone has a later model mustang with hydroboost perferably the SN-95 (96-2004, prefer 2003-2004) variety would you mind telling me what the pedal ratio is.
