    fuel

    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

    I would first put a 195 stat in the car then I would drop fuel pressure to 38 and work my way up

    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.
