[Chevelle-list] Compression Test

[Johnny Palmer]

I did a compression test on my small block 327..all the cylinders turned up to be very close with the lowest being 152 psi and the highest being 155 psi...I can't find a reference anywhere to see if these numbers are within specs or are too low....Can anyone help me out..???..My engine is burning a little bit of oil and I suspect the valve guides are worn but wanted to do a compression test to check the condition of the rings...
