I purchased a nice Edelbrock RPM manifold at a swap meet and decided to cut off all the extra mounting pedestals , which led to the thought I would polish the intake as well. a GIGANTIC job that I would likely not tackle again. I looked on you tube as usual for tips and did not find many so I thought I would post my experience.
