I'm Awesome
So I have a spare intake manifold at home. As I wait for my bottom end stuff to get machined for my 383 build, I thought I would take a crack at porting the intake manifold.
My goals for this project are very small improvements in flow. If I wanted huge numbers, I would ditch the stock manifold/injection system. I'm not looking to rework the runners in a big way. I'm more scared of having a negative impact on flow, but without access to a flowbench.... it's all just guessing.
The stock lower vortec manifold has a lot of cast in ridges surrounding the ports. I have about 3 hours into this so far with a flame shaped carbide burr. Next up is 80 grit cartridge rolls, followed by 100, and 120s.
I'm open to any criticism, critique, or advise anyone with experience porting might have for me. This is my first attempt at this, sobi expect there is a lot of room for improvement. I'll update as I make progress
