170 for 225 SWAP - '62 VALIANT

Depends on the year of the engine. A 68 or newer engine needs a crankshaft adapter bushing (I have these available), if useing the 67 or older auto trans. Might have to modify the exhaust pipe (sometime yes, sometime no) where it comes up to the engine. The 225 manifold outlet is 1 1/2 inches higher, then the 170. You also must use the 66 and older oil pan and pump pickup tube, and the original car motor mounts/brackets.
