Ported TB and LS6

How much hp can a LS6 intake and stock ported TB support on a 346? I'm sure there is some subjectivity to this, but est?? My cam lift is .600 and heads flow 301 at .600, if that is even relevant.

Thank you for the reply, but I was leaning more towards how much total engine hp it will support. Like 400, 450, 600 rwhp.

700 hp is alot! The Fast stuff is pricey but its been proven to do good things. A painted Fast is beautiful under the hood also

I agree, but tapped out at the moment, and just assembled the short block yesterday. I'll get it together and see how the tune goes. A neighbor at the shop is heas of R&D at Painless Wiring, and told me a stock LS1 TB flows something like 800 cfm.
