Re-installing Cam Sensor/Finding #1 TDC?

So I just put in a new 3.0l in my truck. This new engine is missing the cam sensor/synch. So I need to put in a new one.
What's the set up for getting that 38* angle on the sensor and what is the procedure for finding TDC on #1 cylinder.

Thanks!

How to

take and put all the plugs in and leave the #1 cyl plug out take a socket with extension and turn the crank with your finger in the plugs place and keep turning till you hear the air forced out and there is TDC.

Ignition Timing 10 degrees BTDC



straight from the Ford Service DVD. It's on a Taurus/Tempo/Probe/Sable/Topaz, but you get the idea

Engine went in fine.
They really did change quite a few things from 2000 to 2001....which I'm in the process of converting.
-Fat "Green top" injectors in '00 with the square plug - Skinny Blacks in '01 with the oval plug
-Coil pack on bracket in '00 - Coil pack on pass. valve cover in '01 (with different spark wires and coil pack control plug/socket)
-Valve covers are different because of above.
-Exhaust manifold to downpipe. The spacing on the studs is wider on the '01 so the '00 flange doesn't fit (annoying...just have to elongate the holes)
-Wire harness is different because of the coil pack and injector plugs.

Everything else "looks" the same so far. Don't have it running yet...so we'll see.

Keep in mind that there are two instances of #1 TDC in each 4-cycle sequence. The CMP sensor must be timed to #1 TDC at the end of the compression stroke, not the exhaust stroke. You can determine which TDC it is by watching the rocker arms on #1.

Both valves will be fully closed at TDC at the end of the compression stroke.
Both will be slightly open at exhaust TDC.
