This is the NA manifold with a valve that selects between the high rpm (short runner length) and the low rpm (long Runner lenght) intake paths. If someone would so kind as to measure the distance of both the primary and secondary runners. Take the measure from the surface of the lower manifold that bolts to the block throught that manifold, thought the upper manifold through the control valve to the other manifold exit (this is the high rpm/short runner). Do this for both primary and secondary. Then do the same thing except run the string/tape measure from the manfiold face the long route (by passing the valve) up into the face of the dynamic chamber the throttle body bolts to for both primary and secondary. I'll then multiply that distance by two to get the total lenght for the long route (unless you want to weave the string through the second half).
