Okay. So I bought a few 5.3s as spares for insurance and I know one was from an 03 or 05 I can't remember but it is iron block and had 706 heads on it and is a GEN 3. The second one I have no idea the year, but it is a GEN IV iron block and 243 heads. Okay I didn't Eden know that there are two different type of cathedral intakes a NBS and a NNBS until yesterday when someone asked me in one of my adds, so I pulled the for sale as so I could do more research. yes I know they look different, but I was assuming they were still the same intake per say. Ok so here are the pics





Is there anyone who can tell me by the pics if the one on the left in the first pic is the NNBS and one on right in first pic is a NBS? I tried searching for part numbers to check on each intake but my google skills are weak today and couldn't find anything. I am assuming and guessing the NNBS is left and NBS is right? Thanks guys

The one on the left in first pic came on the gen IV with 243 heads if that helps

Yes the one on the left with the fuel rails on it is a NNBS/TBSS style intake with a 87mm TB, the one on the right is the NBS style intake with a 78mm TB.
