Duke:
based on your endorsement, I just purchased EA 3.2. Would you mind sharing the settings for intake and heads assuming LS6 pieces? Without knowing cylinder intake runner diameter, I have to guess at runner length.
TIA

I don't actually have a model for the LS6 heads - but there may be a LS6 head model in the program library.
I did build a model for the LS7 heads. Basically what you need to build a head model is port volume, port lengh, flow data, valve sizes, and compression ratio.
If there is no model in the V3.2 library that's included with the program, I'm sure the data you need to build a model is out there if you do a little digging. The C5 Z06 forum is probaby a good place to start.

Any chance you could share your LS7 intake dimensions? I started modeling my LS7 tonight. I captured some decent cam and max flow number for the head/cam. Intake dimensions are my bottleneck currently.
