Looking to find out what the actual compression test numbers are supposed to be. I read in one post around 220. but this is a stock block with a cam. So I want to make sure of this before I test and get numbers all mixed up.

I'd like to know as well.... esp. if anyone knows for a 383.

As long as they are all within 10% of eachother. Between 160 and 220 seems to be the norm depending on mileage, etc.
