I have this program but I am unsure what to input for the stock lt1 manifold. Most of the included files are carb intakes. There are a lot more parameters in the Pro version and while I was able to input the rest of the engine but I am clueless on the manifold.

If anyone can offer assistance/files/websites etc. let me know. If someone has a file of an lt1 engine just e-mail it to me. Thanks

I heard this is much more accurate than dd2000 anyone have good/bad experiences with this software?

 

anyone ever flowbenched an lt1 intake?
