Compression

What should compression pressures be for a 79' 360, if it matters it's in a 4x4 Ramcharger?

Re: Compression

I,ll tell you the same thing an old timer told me [and it pretty much holds true to this day ] here go,s- under a 100 pounds per cylinder JUNK IT - a 100 or better with run it - a 125 or better will run it down the street - a 150 or better will burn the tires off / you wont get more than that unless its a new motor / the motor must be completely warmed up with all plugs removed and the carb wide open when you check it / good luck

Re: Compression

I forgot to hold the throttle open when I did it so which way would that make the readings go, up or down. The highest I got was 140 and the lowest I got was 130 but it was pretty even across.

Re: Compression

it wont change the readings to much but with the carb closed it draws gas into the motor and can flood it out / 130 - 140 aint to bad at all
