Sure. It was tested after it had run over 100,000 miles to see if the motor would take boost given we're also about to tighten quench with a slightly thinner head gaskets and so compression was going to go up a bit too.
The old girl was between 7-8% on all 8 pots and had 155-160psi compression
Several oil changes previously I had added Militec-1 to the engine, trans, and diff and that might have contributed to the engine being in such good condition.... of course that might have been normal anyway
