Today I made the exhaust system for the 54 F100.  I used a 2-1/2" BBK offroad Fox Mustang 5.0 H-pipe and the mufflers salvaged from Al McGee's 65 fastback, plus the original tips off my 2007 Mustang GT.  The tips are temporary until I install the Mustang gas tank and determine how much room is left for tailpipes.  The 5.0 engine has shorty ceramic coated headers that fit a Fox also.

Main reason I am posting this is for 6sally6.  I figured this is an exhaust system he would appreciate.  And maybe give others some ideas or incentive to do their own system.  Those cheezy muffler clamps and hangers will go away once the tailpipes are installed and I place the permanent hangers.





Since the subject of serpentine belt routing came up the other day, this is just a pic to show how I did this one.  The system is from the 89 Lincoln Mark VII and has a couple of subtle variations from the same year Mustang setup.


Engine stands custom built for the Crown Vic conversion.  I made them to fit 66 Mustang rubber mounts because I like to use parts that are readily available and inexpensive.


I used a 66 Mustang shifter supplied by Josh-kabob and mathematically determined the lever ratio and built the actuation rod from 3/8" steel dowel with spherical rod ends.  I threaded the rod so it has about 1/4" adjustment.
I am still looking for a kickdown lever to go on this C6 automatic transmission if anyone has one laying around.  I plan to make it cable activated.  The seal was already shot before the welding took place, so it will get repaired once this thing is roadworthy.  The kickdown lever goes on the 1/2" nut pictured by the weld bead attaching the lever arm.  The tranny was from a column shift truck so the lever was pointing the wrong direction for a floor shifter.


Trans coolant lines run along the passenger frame rail up to the radiator, with plenty of bends to take up any movement.  The loop to the rear was to clear H-pipe not yet installed.


One thing nobody tells you when installing a Crown Vic front end on an old truck.  The LCA rear bushings are mounted at a 45 degree angle on the crown vic.  When you put them on a truck, they get mounted flat.  There is an adjustment slot in the bushing so the caster can be adjusted by moving the LCA rear pivot in or outboard.  That adjustment will not be there in the proper location if you do not cut the round steel bushing housing off and reweld it at a different angle so that slot is parallel to the ground.  The red dashed line shows how it would be angled if not rotated like the red rectangle position.
