thanx Rocky, well you would think that the 72 ho carb having its own part #( different than the standard 455) and being for a "ho" motor would flow more!( especially w/ ram air) according to the book it does. Soo, does anybody have a 72 ho carb that can look at the venturis , and tell us if in fact the booster ring is in fact removed for more flow according to the books!! ( hopefully someone can tell us if pontiac scimped a little on their 72 ho carbs!!??) weelll seee thanx all, Forrest
