TOPIC: 1958 Totem Craft hull engine info???

I am new to the classic boat thing and just got a 1958 Totem Craft It mesures about 14' from bow to stern and was originaly equiped with a Mercury engine. It has a Cat type front hull going to a flat bottom in the stern. The transon is about 14" tall. I am wondering if anyone has any knowledge about these hulls and what would be a good 1958 to 1963 era engine to run on it? Bigger the better I am wondering if a mark 55 would be too small and if a mark 75 or 78 or even a mercury 1000 would be better and still somewhat safe?
thank you for any info you may have on this hull and or opinions.
