I drove a truck with a three gauge pillar mount, I'm 5'5'' so to mean it seems like it can hide cars behind it.

Would 30 psi be a safe boost pressure so I do not have to worry about the head gasket blowing out, I have seen that they can blow anywhere from 35-45psi

If you installed studs and Machined rocker pedestal's .. you can run 60# give or take ..

Its all about cylinder pressure .. if you bump your timing you increase cyl pressure
If you add boost pressure you increase fuel .... ETC .. all of these together are what pops a HG ..

You need to spend wisely, put your money into insurance that's guaranteed to be a good step forward ..

Other wise you CAN run 100# boost .. wont last long and no one knows when they will pop .....

One way you WILL pop the HG is high EGT's when the engine is cold .. I was racin mine when it was cold .. didnt know you could vaporize the coolant in the head .. pressurized the HG to failure .. now I know !!!

That blows. I finally change out my main crank seal after the leak just became a pia. Now I have to change the brakes this weekend
