looking for 340 tripower and ...........

hi folks I am looking for a 340 tripower set up. I thing I found a set of carbs but I need an intake for sure. would consider a complete set up. I know there 3k from mopar (complete) so I am certainly trying to beat that price. or get an intake. also need a factory tach and dash face that will accept it for a 73 duster, a center console , and some headman headers thanks pm me if you have a line on any of this stuff
regards BFB
