OK got the results.
I am not very familiar with chevy's but a 355 is a 350 bored 0.030" over, correct?
The results are valid for testing the engine on a dyno:
- No exhaust system
- Electric waterpump and fan

Dynamic compression: 7.72
Theoretical cranking compression: 192psi
Idle vacuum: 11,7" Hg


Info you minimally need for a decent result:
Block:
- bore x stroke
Head:
-flow for intake and exhaust
-valve sizes
-compression
-squish<0.060" yes/no
and preferably port lengths and diameters at faces
Intake:
-type of manifold
-cfm of carb
and preferably port lengths and diameters at faces
Exhaust:
-primary pipe diameter
-primary pipe length
Cam:
-type of cam
-open and closing events @0,050"
-cam lift
-rocker ratio
and further type of fuel if not gasoline
