stock compression?
I have a 1989 2.8 v6. and i was wondering what the stock compression was. They reccomend 8.0-9.5 for the cam i'm looking to get. Do you even need that done

yeh, 8.9 to one is the factory compression, and yes after time the car will start going down a tad, the easiest way to tell if things are still in working order is to do a compression check, you should be able to pick the guage up at any autoparts store, and there will probably be instructios in te pack along with a haynes manual.
