Autocad Drawings for Manufacturing Auto Engine Parts

We require an autocad drawing for overseas manufacturers to use for casting aluminum intake manifolds, and for creating some CNC parts. The initial job on offer here is to create the drawing from a physical intake manifold, and a physical carburetor spacer. The intake manifold is a cast item, and the spacer is a CNC machined item. See attached photos. We will ship via UPS two items. You will be expected to measure the items, and create a working blueprint in autocad suitable for a factory to create a copies of the parts. If the work is successful, we have several dozen items we will require the same process on. We expect a turnaround of no more than 1 week from receipt of the sample items. Once completed the sample items will be shipped back to us using a returns label we will supply.
