Lifelong machinist and have been a CNC machinist/programmer for the last 20 years with a leader in the prosthetic industry. I machine a lot of castings we make for this industry including titanium, cast iron, aluminum and magnesium making a lot of billet stuff as well and a lot of carbon fiber. I have made quite a few intake manifolds patterns and cast them for some niche automotive markets as a hobby. It's great to be with so many like minded individuals....
Here are some pics of the intakes I've had cast. The dual Weber side draft intake in the top pic is for the early Chevy II 4 cylinder engine, and the triple side draft intake is for the bigger brother to the 4 cylinder engines, the 194-292 Chevy 6 cylinders. Im trying to find some pattern pics now to post....
