Curious as to what this guys automotive background is that he can make a blind statement like that. Everything looks good, and with a competent tuner I don't see what the problem is. As previously stated don't go to crazy with the boost and have fun. I know someone who had a stock bottom end low mileage LT1 running 7psi of boost and a good tune last something like 12 years. And he only rebuilt it because he got bored and went a different route with his build.
EDIT: I'd like to note that his car was a seasonal car only and he only drove it like 3-4 times a week weather permitting.

This guy... He claims hes a prototype engineer
Calls him himself mathematical engineer
Says that numbers on my build are 15 static
I confirmed with like with diamond, lloyd , calies everyone told me around 9.2 and 9.35
I thought guy was bullshitting but hes dead serious, says he uses math every day... and has built 4 race spec motor even calculated 3 angle vavle jobs on how it will affect compression.. guy is either a meth head or a ******* genius.. i cant wrap my head around it

Lol yea i figured that I found this calculator
https://www.rbracing-rsr.com/comprAdvHD.htm
But i dont know the ab what ever that was so i cant be accurate
.i just put 50 as the number and my dynamic sits a 7.0

I made some assumptions like you are using the typical Felpro blower gasket and I got 9.22 with zero deck height. To find dynamic you need to find the specs on your cam. Not sure what this guy is on about but some people have no lives and like to waste time arguing on the internet.
