compression check

Is there a safe way to check the compression of a 200ci engine that is not installed? I plan to swap my blown 200 with another, but I want to make sure the other engine is OK before putting all the labor into the swap.
 
The engine in question was removed from a 66 mustang which is receiving a V8 swap. The engine was reported to be in good working order, but you know how that goes. I received the engine and trans for free, so I can't complain.

As for my facilities, I only have a 2 car garage, hand tools, and an engine lift available to me. Very limited. Sounds like I'll need some extra help on this one, huh?
 
Just put the starter on it and rig up a few cables to a battery and crank away.

Just be careful with your fingers.
 
If you can make the facilities suit, I'd suggest the following menu:

Pull the head, with associated rocker gear retained in correct order, and inspect the bores. If it all checks OK, drop the oil pan.

Flip the motor and check the thrust bearing, and the rear main. Assuming both are fine, replace rear main oil seal as per the directions of Ford and using the Lexus sealant recommended by wsa III. The 1/32" end offset is important.

Replace front oil seal in timing cover and be prepared to buy a sleeve for the balancer's seal running surface. Take care to seat the timing cover about the balancer, for maximum seal effect. With due care, reinstall oil pan to correct torque.

Turn the motor sunny side up, clean the head bolt threads with greased plug tap, and protect the motor top with rags or thick paper. Install the motor headless, as it will be smaller and lighter to do so. Reinstall the head (as discussed many time elsaewhere in the forum). :wink: Fit your ancillaries, and go for it!
