i'm also using the long rams in my 33 dodge humpback panel truck, so i already know "they won't work". my plan is basically the same as the OP. as i can go up [no hood], i'm planing 2" spacer/adapters for the manifolds to throttle bodies, plus cutting [from the undersides] the dividers out, making them short rams. also keeping the divider and using it for the map sensor. i'm also considering fabbing plates to position the injectors at the head ports, but at this time, not put much thought into that deal.
continue on please.
