"1975 Plyouth Duster" Model

Hmmm.. Is that the new three barrel intake manifold made specifically for the double probationary s/b head? :tongue9:

Actually, I think I remember Holley making a three barrel in the late seventies or early eighties. The single large secondary was directly behind the two primaries. Didn't really catch on though.


I vaguely remember reading somewhere that GM might have used these on a Corvette back in the 60's.
