Ok, being a regular user of Wow-Pro guides, I leveled my first Engineer to 375 and seeing the lack of a guide to help rise the last 75 skill points, y compiled what I think is the easiest and less expensive way to reach this goal.

Whenever you create "parts" to skill up, keep them - don´t sell them, you will be using them some time in the near future.
.
Most of the schematics are learned from the trainers, but the last 15 points will require some receipe grinding. Each require you to grind on specific mobs till the receipe drops for you (click on the wowhead link to see who drop´s what). These are BoP and can not be found in the AH.
.
More than one item in a level range means that you can choose which one to craft for the given range.

Here is the list:
.
.
300-310 Handful of Fel Iron Bolts = 1xFel Iron Bar
300-310 Elemental Blasting Powder = 1xMote of Fire + 2xMote of Earth
300-310 Fel Iron Casing = 3xFel Iron Bar
.
.
310-320 Fel Iron Bomb = 1xFel Iron Casing + 2xHandful of Fel Iron Bolts + 1xElemental Blasting Powder
310-320 Fel Iron Shells = 2xFel Iron Bar + 1xElemental Blasting Powder
