Been busy working on other parts of the car but getting ready to take a look at the engine stuff I have on hand. I’m not even close to being a small block Chevy guy so I’m learning, reading, etc. on them. I still have to pull the valve covers off the (alleged) 327 and check the casting numbers but I’ve read that the 882 heads are boat anchors. We’ll see what they are. Should be able to take a closer look this weekend.Looks like the head on the driver side has the markings of an 882 head.
Which was ran from 1971-1976 on 350-400" engines and have 76cc chambers but I have measured them and found some were larger.
Not much compression from a 327" if that is a 327" and flat top piston engine.
You can take a straw or zip tie and insert it into the spark plug hole and turn the engine by hand and find the point where the piston bottoms out.
Straw no longer goes down. make a mark on the straw and one on the head or valve cover next to the straw mark.
Then turn the engine and the straw will come up with the piston.
When it is at it tallest height make a mark on the straw next to the mark on the head.
Measure the distance between the 2 marks on the straw.
3.48" or so will be a 350" stroke which is the same as a 305 chevy.
3.25" is the 327" stroke.
