What size pulley are you running. I have a 3.50 on my P1SC and I am only getting around 6.5 to 7 psi according to my gage. My gage might be off but if I am going to bigger Injectors, I might as well go with a smaller pulley to up my boost

Your probably already slipping the belt with a 3.5 That is why your only seeing 6.5psi

CantHook - I realize this is not what you want to hear, but, American_HP is *right* on. Your cam is a bit small for a 427, worse still is your choice of head-units (P-1SC is pretty tiny for a big cube motor) and your injectors are WAY too small.
I would start with a minimum of a D-1SC - you can get ATI to upgrade your existing P-1SC head-unit for around a grand. Also make sure you start with an eight rib kit.
I would start with 60 # injectors with a blown 427 setup.
Good Luck,
Mark
