The stock '82 engine in FrankenSpider tested at 165/150/135/155 when we 
first got it running: too uneven. That's why I decided have the head 
pulled, check the valves and seats, and do a set of pistons and liners. I 
haven't tested compression since fitting the new 10.4:1 pistons.

Are you sure that full throttle was used when you made the compression 
readings? From the evenness of your readings, it seems like the engine is 
worn extremely evenly if those are accurate readings. How many miles does 
it have on it?

I'd suggest rechecking the compression once more to be sure you're really 
getting those low readings.
