How much compression should you get out of a 95 350 freshly rebuilt bored 30 over?

I did my chev 350 and I got 150 psi before running the motor.
Second, what's your altitude? When you check the compression at low altitude it will be noticeably different than at higher altitude.
Third, how are you "cranking" the engine? if you're just using the starter, you may not get a lot of compression because of the low cranking speed.
Fourth, what lubricants did you use for assembly? If friction is a little high, again, you won't be able to crank the engine very fast.
Another variable will be the pistons; if you've used high compression pistons the compression will be up. If you've used traditional pistons... not so much.
Another OpinionYou should get at least 175 psi to 188 psi
