compression test

[dart gt]

I did a compression test on my 68 318 before i take it out to paint.The drivers side from front to back was 145,132,145,160 and the passenger side was 150,150,175,145.What im worried about is the 132 and the 175.can anyone tell me if this is alright or do i have a problem.Thanks David

While it could use a freshening it's probably not about to grenade

First did you have all the spark plugs out as you were doing the test, you should have. Second, did you have the carb throttle blades wide open, you should have? When you do the test you want 4 good pulses on the guage then stop at 4 and have each cylinder do 4 pulses.
