Left over from a high performance warehouse accusation and I had to pull the staples out of the box to take the photos. Brand spankin’ new piece. The most unique feature of this Holley single plane Keith Dorton Signature series intake manifold for Chevy small blocks is the 3-part construction. The plenum, valley cover and intake runners are each separate pieces, which can make certain porting and internal modification chores a lot easier if you need to do any. But the power they produce for drag racers and circle track competitors--from 4,500 rpm all the way to 8,500 rpm--is the big attraction. It's designed for the 4150/ 4160 performance carburetor bolt pattern.
