Since big blocks in E-bodies became a thing of the past in 1972, we can refer to the 1970 and 1971 K-frames and their part numbers and see what fit what:
1970: 225CI, Part #2962010; 318, 340, 383 & 440CI, Part #3466477; 426, Part #2962014
1971: 198 & 225CI, Part #3583070; 318, 340, 383 & 440CI, Part #3583074; 426CI, Part #3583076
As far as I know, the K-frames for the Challengers and the Barracuda E-bodies were the same. It seems your 440 should fit the 73 Cuda small block K-frame, but you might want to check with Schumacher Creative Services. 206/364-7151.
