Default Re: “Inside” part of road draft tube

This particular valve is a Borg Warner PV255. It is built to use horizontally. Same valve that’s used on the road draft tube of a mid-late 60s SBC. 1/4” pipe thread on block end.
Hope it works well. At least the flow is in the correct direction! They are a bit hard to find.
