Autoline products is no different than any other mass ruiner of good cores. I purchased a BBD from rockauto that was done by them. The base was belt sanded to make it flat (not) and the throttle shaft was loose as hell. Take it all apart and see where they left the throttle shaft and blades installed when they sand blasted the base casting. A mismatched pile of junk in every respect. Their sales pitch is fluff and nothing more.
