3.0l vulcan engine has unique trans bolt pattern, no other engine uses that pattern.
So replace it with 3.0l or go for full V8 swap
3.0l Vulcan engine was also used in Ford Taurus and Mercury Sable cars, front wheel drive.
It has a different cam than the Ranger 3.0l, more horse power but less torque, but most say it isn't noticeable.
Since the cooling system on the cars has coolant going in the back of the motor and out the front the head gasket design is different for the car 3.0l.
If using car engine in a Ranger it is recommended that you change head gaskets to Ranger model, but again people who have done that swap say it didn't matter.
I would do it though.
Also used Aerostar and windstar vans
