Engine Compression test (what values to expect)

[Cuprafenix]

Hi I'm restoring my Williams, so disassembled it completely including the engine.

As I have two engines gonna fit the best one, but before that gonna make a cylinder compression test.

What values should I expect to obtain?

Any help would be appreciated

150psi should be good from what I'm told.

Mine made 190-195-195-190 (or else was 195-190-190-195)

Mine did 185-190 across the board with 200k miles on the clock

Did the test and the value where around 13bar, 189 psi. Think the engine is around 100.000 miles

[Coops]

spot on provided all within around 5-10% of each other

So this engine is healthy
