I like the work on the valve cover. Is that dark grey paint or powder coat?

As to the gears, I have just changed the rear gears on my truck to the 4.625 from the 3.909 and like it much better. My plan is to use 33" tires, achieving the same as stock drive ratio.

There is a gent on maxd50scene.com that used a long, slender intercooler under the front bumper...still wanted to use the factory A.C. system.
