I just picked up my F54 block, crank, and rods today, and going to take it down to be rebuilt soon for a relatively mean turbo build. What oil pan is reccomended? I remember when swapping a 78 Z motor into my 79 Z, I had to swap oil pans for it to clear the front crossmember. Now I don't know if that HAS to be done, or maybe we just weren't wrestling it in right. Anyways, do I need the F54 turbo motor oil pan, or will just a NA 280 oil pan be fine? Also, is the Arizona Z car aluminum one worth it?
