With an 068, I can run a lazier rear gear for less road rpm and less wear and tear, which gives me guiet cruising and high MPG's. Ram air cams want a stiff rear and gear and make power at high rpms. Great on the track, but for me on the street, not my bag. This '67 with an o68 cam, TH400, original 400 engine, Q-jet, points distributor and swapped in 2.56 rear end averaged 20.6 MPG on a 2700 mile cross country trip in 2023. Car has 260,000 miles on it, engine was rebuilt 90,000 miles ago. Attachment 660262
