so if im reading the document you posted correctly

it shows that the t-quad and avs ARE the same height, is that correct?

because the avs was used on both 69 383 and 440 motors

and im sure that the small round air filter is taller, than the large oval air filter, i havent measured them but id guess about an inch different in height, which therefore would explain the height difference in the base

i did just measure a t-quad and ave and they are the same height from the bottom to the surface where the air ceaner sits, so the carbs are the same height

i remember years ago when ken s was at my place looking at 340 shaker baseplates and i thought he was telling me how he thought the 71 tquad base was a different height then the 70 avs base
