Knowing the year would make a difference. A good STOCK 350 should have at least 150 PSI per cylinder. You CAN'T have any more then a 20 LB difference in any giving cylinder are you will have idling problems.
The compression ratio of a 350 Chevy engine usually ranges from 8.0 and 9.0 to 1. This provides a good balance of fuel economy and power.
4.000x3.750 with 8.5:1 compression
around 80 ft.llbs. or higher is usually good.
150 psi should not vary by more than 10 psi between cylinders
Compression ratio on a 1974 Chevy 350 in a Nova was 8.5:1.
1976 Chevy 350 engine should take 5 qts engine oil with filter change.

Remove all the spark plugs and turn the engine over by hand. Place your thumb over the #1 plug hole and you will feel the pressure on the compression stroke. A compression gage will also tell you when you are on the compression stroke.
8.5 to 1 compression is factory stock.
About 8.5 to 1
10.5-1
Chevy didn't make a 350 engine in 2001
