if you are going to try to make a t-ram from a 429 wedge fit,its a lot of work.i did a victor intake and it did fit and run great on a boss 509,but in the end it cost me almost $900 in 2010.you have to weld on the flange for reinforcing it after you machine the intake face, and to modify/make new most of the bolt hole bosses.the boss intake face is a differnt angle than the wedge.
the reallity is that the guys who are asking stupid money for them will NEVER get it,because no one needs or wants them for a real boss car.keep looking for one,or use a kaase single 4 untill you find one.
if you know spmeone that can tig weld,and machine the face,it can be done.
also welded flat aluminum between runners to support intake face.once you mill it to fit engine it gets pretty thin!
