Way random. Depends on your fuel system, your camshaft, and tune...

I wouldn't go any more than 8 psi. You need a real fuel system, that's the limiting factor. [ August 21, 2010, 11:30 PM: Message edited by: JohnB ]

Either ditch the pulley for a 8 psi or less setup, or upgrade your fuel system.
Or, just change head gaskets every time you pop one. Run a 9333PT1 FelPro gasket.

An e cam in a 347 aftermarket block with boost? Really? The cam is gonna hold you way back. You can make power in spite of the cam, but it's time to step up the bumpstick. [ August 22, 2010, 07:47 PM: Message edited by: phildog ]

i think johnb is saying magnafuel or aeromotive something that will support a lot of hp. You do not want to run out of fuel and detonate. On my cobra i had a a1000 with 10 an supply and 8an return. got a sumped tank and aeromotive setup if your interested. pics are in my profile.
