'CHA54' is the only member on here I can think of that would know that figure off the top of their head.

180 - 200 would indicate a healthy motor...

If the compression is down around 150 - 160 and then boosts up to 180 with a squirt of oil then it's a good indication the rings are wearing...

Factory compression test specs for the 9.4:1 ratio bigport 4age are 179psi down to a min of 142psi with no more than 14psi difference between cylinders. I'd expect your 8.0:1 bigport 4agze to read a lot lower than 180psi with a normal compression test, somewhere closer to 160psi would indicate a very healthy engine.

I'd be more concerned about getting very similar numbers across the cylinders than just a figure. 150+ is good for most low comp engines.
