Call Dave and talk to him. After he explains to you how stupid you are you will probably never buy anything from him. Big hint:. Don't mention Moparts to him unless you really want the conversation to go off the rails.
If you decide that you just have to have one of his cams, bypass him and get it from the source.
I recall him posting a little diatribe against Moparts years ago when some of the members built an engine for some contest. Calling them amateurs and looking down his nose.
Decided right then and there he was a vendor I chose not to support.
