a badge? like a "350" badge? more likely a model number or it was added w/ the 350, which weren't made in 59
don't have a mount pic handy, but the shop manual should tell ya - if it's mounted as original, it's got 2 wimpy lookin pegs from the front of the block to riveted on mounts on the front crossmember, and the bellhouse has ears that mount on the cross member there - the tranny hangs off the bellhouse - more likely w/ the 350, they put a cross member under the engine at the point where the side mounts are, which is a standard aftermarket conversion
here's some
good pics of my V8 truck
