You're pretty much limited to the same engine from a 1986~2006 Concours.  There are no easy upgrades.  A ZRX1200 motor can be made to work, but the work includes custom fabbing some parts.

Don't be hung up on the word 'newer', as a good older engine beats a bad newer engine any day.

Even a high mileage, older engine that is in good condition might be better than a low mileage, newer engine that has been thrashed, or not cared for, or hydro-locked.

86-06 will all work, 86 apparently had some issues with tuliping valves. Starter, alternator, etc apparently are all the same

Any year C-10 motor will work.
There are a few others that can be made to work, but {I think} all require changing the motor from chain to driveshaft...

If your looking for more power, the C-10 motor can be modified easier than changing to another engine.

 
Ride safe, Ted

A good repair manual will be a great help for your project.

There are 4 engine mount bolts. 

Also:

Be discriminate with any rubber bits and anything that seals since you are dealing with a 30 year old engine.

While not an exhaustive list, some things I can recall off hand to preventatively replace / service before / during engine install, since you'll have easy access to them:

- Check / replace clutch star springs.

- Check alternator chain and alternator chain tensioner (ACT) integrity.

- Replace mount bolts for the side stand switch.  I changed mine from hex head to lower profile standard bolt heads.  OEM hex heads required header and / or center stand removal IIRC just to remove side stand switch. 

- Coolant log and T-stat O-rings.  (While in bike, front log requires header and radiator removal to get at.  Rear log and T-stat requires carb bank removal.)

- Seals for water pump (3), shift shaft, clutch push rod and balancer shaft.

- neutral switch and oil pressure switch washers.

- Oil lines washers.

- Any gaskets showing signs of leaks.

- Radiator hoses.

- Do your first valve adjust before installation.  Super easy with engine on the bench and everything already out of the way.

- get any needed carb servicing done before you put the bank back in.
