Old post but for readers of this post it was Car Craft or Hot Rod that tested every intake the could get their hands on and the #1 was the RPM air gap and the 340 torker was #2 and so cloose it was a wash and just as good..Why,because as cast the 340 torker is a smallish runner with excelent port to head layout so as the name says,it's a torquer and works good up top too.,They look good too.
