Edlebrock was giving shop tours yesterday. I guess they do them about once a year. Not sure how or why, but I was sent an email invitation over a month ago. So I reserved a spot and took the drive down to Torrance yesterday to participate.
It's pretty amazing the technology they have at their disposal to R&D, manufacture, and do quality control checks. I would highly recommend taking the tour if you ever get a chance.
They have one of those 3D printers in R&D to make partial hard plastic models of cylinder head designs. Had one running when we were there. I thought that was pretty cool. Heard of these 3D printers but this was my first experience seeing one in action. How long before one is in nearly every home? Ten years maybe? They use this 3D printer to make up prototypes and test air flow designs before ever making a casting. They also use the models to build tooling and lower R&D time as the cores are being cast.
Anyways I had forgot all about these heads so I didn't even think about asking.
Pretty cool to see an American built product here in California no less, that is being successfully produced and employing so many people. They really do look like they have their act together even if they are taking there time with these heads.
