That is a W2 dual plain intake for use with W2 heads. for low end torque off the turns in roundy round or Trans am racing. I saw it and was interested but it has been cut for an extremely decked block. More then likely 900 deck height which was common. for Trans am racing or oval track short stroke. Note the holes have also been ovaled for fitment to the decked block. Basically a wall hanger. Its far from equivalent to a standard LD340
T/A heads were identical ports to 340 915 castings. The only difference was relocated pushrod hole so the pushrod bump can be ported out of the intake port.
