How do you tell if your 97 f150 4.6 is a Romeo or windsor? Someone told me that if your 8th digit of your vin is a 6 it's a windsor and if its a w it's a Romeo , does this sound rite?

 

Apparently that would be the case according to this other thread:

You got it right.
GOOD LUCK.

 

what is this post about????

 

The post is about how to tell the differences of some motors that are same size but made at different plants such as the 4.6ltr. Here are a few of the differences:

REP (Romeo Engine Plant) motors have 11 bolts on the left valve cover, WEP (Windsor Engine Plant) motors have 13.

Camshafts sprockets are retained differently between the two and the TDC camshaft alignments are different.

Water pump hose under the intake manifold is retained differently, REP is clamp, WEP is metal tube and nut.

REP Crankshaft main caps have 2 main cap bolts, 2 jack screws, 2 side bolts. WEP crank main caps have bolts, dowel pins, but no jackscrews.

Number of thrust washers on the last crank journal are different.

Crank main cap torque specs are different.

 

Thanks man very interesting good info to know my wifes is a 01 f150 5.4L. So there would be differences for this motor to.

 

No, 5.4's for trucks were only built in Windsor.
The 4.6 is the one that can be either.

 

Hello, I heard that Ford makes the engines (either the 4.6 or 5.4 or both) out of aluminum for Lincoln and Mustang cars. Which plant makes those? Kira
