1. If you're going to port your own heads, go the wrecking yard first and get a set to practice on, screwing up your own heads will be expensive.
2. :bash: You guys are missing the OBVIOUS point, the reason that a 5.4 makes so much more torque than a 4.6 is the EXACT SAME reason that my 351W makes more torque than a 302: same heads, same bore, LONGER STROKE! Torque is made in the crank stroke, ladies and gentlemen, it's that simple. Careful research and the right parts will do it everytime.
Impressive numbers on the 5.4 dude! If I weren't so disillusioned by my first experience of stuffing a motor into a Mustang that it wasn't meant to have, I'd be hunting for a block myself. Try a longer rod next time for a better rod to stroke ratio, you'll see some sic numbers in RPM and torque then.
