I would like to know how much it would cost to rebuild a 351 windsor engine. I'm not sure how much horsepower it currently has but I would like to add about 100 more horsepower to it. I also plan on taking it out of the Crown Vic and putting it in a mustang body.

Take it out of the CV and put it in a Mustang?! BLASPHEMY!!

Rebuilt, you're looking around $800-1200, depending on who does it. I wouldn't trust anything cheaper than that.

For more power, get your heads ported, add a good cam and a better intake and you should be happy. If you're running a VV, ditch it and get a Holley, Edelbrock, or Carter.

Anything else?

Yep check clearances,it may only need new rings and bearings...
As with most Windsors, power is in induction especially efi...
New oil pump, rod bolts,head bolts and while pan is off fit windage tray if there isn't one...

Yes, he's right- be sure to install new oil pump, rod bolts and head bolts, and if you have the money, definitely spring for a windage tray or valley supports. 351W are known for cracking under pressure.

However, if you're going to pull the motor and install new rings and bearings, you should go ahead and have the block cleaned and honed, as well as new cam bearings and freeze plugs installed. That's my opinion.
