Well I just got my Pantera back from Murillo Motorsports. He did my exhaust installation and dyno tune. Here is the data.
Internally Stock 2001 Lincoln Navigator 5.4 DOHC engine
Kinsler Individual runner manifold w/ 2 3/16" diameter throttle bodies and 7" long stacks
Wilkinson 4.6 conversion mid length headers into FAZA exhaust w/ 1 7/8" pipes.
Dyno results are 290 rwhp 330 rwtq
So that is about 330 hp and 380 tq at the flywheel.
That is pretty good for a basically stock engine.
