[FFR428]

I have a Billet Specialties pan that looks just like the Aviad/Armondo pans. It came with a windage tray w/ a stud the pickup bolts to for added support. I remember someone (I think on the FFR forum) having a problem with the race 4.6 pans trap doors not opening and closing properly. Some welding slag and assy issues were found upon further inspection. Maybe check to see if the trap doors are getting hung up on something?? I don't remember who was making those pans for them but they were pretty shabby looking too!!
