351M compression test

Hi,

I was just wondering how a stock 351m would rate in a compression test
when it was new but run in.

The 351M in my bronco only pushes out about 115p which in pretty poor,
and the motor has only done about 50,000 miles.

Are you holding the throttle wide open when you check it ? Not sure if it'll make much difference, but it's worth a try.

No, just pulled a plug out and wound the motor over.
