Horse power will depend on turbo and injection pump setup.
The DT4xx share the same basic block and many components. Early blocks were 1 lifters, later truck 466s were 1.125 lifters and the really late ones were roller lifter.
Later + head is considered desirable as they are supposed to flow better.
Crankshaft stroke is different between the 3 sizes, 414, 436 and 466. 4.75, 5 and 5.35 respectively. Bore is the same at 4.3. Connecting rod is the same, piston pin height changes between the models.
