Re: 401 swap into '62 1500
Everything you want to transfer from the 305D to the 401 will work, you may want to consider using the 401 exhaust manifolds as they have free flowing passages. Another issue is if you want to use the 305 timing cover housing, if you do then you will need to discard the 401 3 piece gear drive and replace it with the 305 double roller timing chain and sprocket which will also require capping the center idles shaft hold with a 1 1/8 expansion plug
