The 69 440 4bl air grabber lid is an oval piece and believe its the same lid as the six packs but has a different base for the 4bl. So your saying the oval lid is warped? Is it also the same gauge thickness as a factory one? The 4bl base will most likely be shortened somewhat to fit a taller intake carb setup so if its not too warped or too thin I was thinking I might be able to make it work or is it complete junk and nothing really to work with?
