well its pretty basic and i thought that i would be a little short of what i should have.
24 lb injectors with calibrated maf. sotck lines, sotck rails and stock fpr.
i just order a afrp and a gauge..what should the pressure be with a 347, tfs tw heads ported, 9:1 c/r, w/ a custom cam .533/.544

What are the details on your 347? Do you have a post w/pics? In process of building my own and looking for some opinions.
