Vacuum Pressure and Potential Brake Issues

[greenweenie1969]

Hey all! I have a 383 stroker crate motor on my 1969 c20 2wd. I have upgraded to front and rear disc brakes from the original drum brakes. I was speaking with another customer of the same engine builder about our setups and he said he had issues with low vacuum pressure do to the larger cam they put in the engines. I spoke with the builder about this and they said it produces 16-19 psi. So I am wondering if that will be enough?

If it is not, what are some better options for master cylinder/booster setups? I planned on replacing the original anyways as this is a frame off so I want to get the proper setup.

Thanks.
