Answer
OOps!   I'll dig back in my archives and insert the first part of the reply below.  

>>>Answer -
The compression test shows that your engine is really in pretty decent condition.  These are not high compression engines - and your cylinders are well within normal limits and variation - 103 +/- 7 PSI is actually quite good for this engine.

Before you go to the trouble of overhauling the engine, give it a good tune-up, and set the timing, dwell, and mixture for optimum running.  Set the timing so that you just barely hear pinging on acceleration in top gear at 30 MPH with light to moderate acceleration.  The pinging should stop when you give it more gas, if it does not, check your vacuum advance unit for a vacuum leak.  If you still think it is really too sluggish, check the valve timing, it is possible that your timing chain is stretched beyond spec, depending on how many miles on it.  If it has less than about 150,000, I wouldn't worry about the timing chain.

These are very heavy cars, with a quite small engine for the weight - they never were quick to accelerate - even the supercharged 54's were pretty
slow.   My advice is to enjoy the car for its comfort and beautiful lines,
and don't expect it to keep up with modern traffic - it wasn't designed to do that.

The rear main seal leaking is true of almost all of these cars - it
doesn't hurt a thing except the looks of your garage floor.   Even a
complete rebuild is not guaranteed to stop all the leaks - especially the rear main seal - they are famous for leaking!

I personally enjoy rebuilding engines, so go ahead if it will bring you pleasure, but don't expect much in the way of performance improvement.

Good Luck

Dick.
