Is the Lunati crank and rods capable of reaching these rpm levels and more importantly can set of LS6 or LQ9 heads flow enough air to support it???

Head flow is the least of your worries. For RPM's like that you need a good intake. One of the expensive sheet metal ones or some sort of custom. LS1/LS6 intakes are going to not flow well up that high <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />

Al is right. the head flow is there absolutely. the intake however, is a totally diffrent story. sure, the motor will turn that high but even with great heads and a cam spec'd for that powerband, even the mighty LS6 intake runs out of air past the 6500 point. might look into a custom sheetmetal intake or even the holley might be enough to work as cheaper alternitave.

Ok, so the bottle neck is once again the intake manifold. I do not have any of my formula's out here on the road with me but what would the intake have to be able to flow to reach 7500 rpm? Once known can either the Weiland or a sheet metal intake flow enough air???

For a 347ci displacement that is.

Oh, and a TT setup may be part of the equation <img border="0" alt="[evil]" title="" src="graemlins/gr_devil.gif" />

Most sheet meatal intakes will flow enough regaurdles. This is something that you might want to talk to your engine builder about for your specific needs.

They haven't been the intake solution we'd hoped it'd have been.
