BuildA-Z

Hey guys. I'm brand new here and need some info. Not new to car forums so I know all about the search function. I was just wondering if anyone could either send me some info on sbc mounts. I would like to build my own seeing as there doesnt look to be a whole lot to them. I have found people saying they've done so, just wondering if anyone has been nice enough to publish dimensions, or if I will have to try to make them by trial and error, make a mess and end up ordering them. thanks folks
