Don't under estimate the HAMB there are serious Inliners there. You just have to search out their threads and groups. It's easier to do searches there. I never go to the main board anymore. It's too busy. There are guys there who race GMCs on the dry lakes and at the drags. Some of them seem to have a lot of money for their projects. A lot of BS too but it's hot rods. Stovebolt site might be a place as well.
