A firend of mine works on Fords and runs into the same problem about engine placement. Just because the trucks are from the same plant doesn't mean everything fits the same. I have two 4x4's with 454's in them. The 1968 I moved the engine Forward aprox. 2" and put 2wd Jethot headers. Small moons had to be made in frame for a good factory look. The 1970 was not moved forward. It has low cut valve covers and the drive side is still tight.
The exhaust manifold is still stock. Both trucks are long wheel base which helps with the extra weight up front, not so much kick. I had to put bigger lug bolts on because of the added weight. Both trucks are 1/2 tons with power steering. The 68 has disc front and rear and the 70 has disc front.
