On the look
 

Will be building a 440 and the 727 from my RV looking for a car to shoe horn it in to . like the look of the 72 dusters but not picky just like them on the smallish and old side (sorry if that makes any one feel old im a model 82 ):argue:

Welcome here man, Im new also, I bought a 73 duster, we dropped a 440 in, 727 tranny, headers are TIGHT, I had to go with shumacher custum headers, and they fity great, they are pricey but so worth it. And yes you damn near need a shoe horn to fit that engine in. Best of luck, and the guys on here are great and help tons. Cant wait to see the project
