Compression test

Hey guys i decided to do a comp test on my motor, just because odometer shows 262,000 i found the comp to be 172-174 in each cyl, i was told that is awesome? usually motors with high mileage have lower comp.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.
