That's amazing!!!
It is a documented fact that Park gained AT MOST 41 pounds of MUSCLE in his entire career (probably slightly less). Even at this, I don't think you even won the bodybuilding competition you entered. (Park would have obviously just embarrassed himself if he had shown up in his 1951 form).
Look about half-way down the page of this article. It is preceded by a table (Table 1) of weights of bodybuilding champions.

I quote:
"Comparing these bodyweights to population averages shows that these champions carry 24-26% more lean body mass than the average person of their height and bone structure.
A large man such as Reg Park would carry 38-41 pounds more muscle than his average, non-weight training counterpart. A smaller structured man, such as 2006 WNBF World Champion Jon Harris, would carry about 31-34 pounds more muscle than an average, non-weight training man of his height and structure. It is also interesting to note that the absolute level of muscle mass carried by modern drug-tested bodybuilders is not statistically greater than that carried by bodybuilders from the pre-drug era - though modern bodybuilders compete at much lower body fat levels."
Jon Harris is 5' - 7.5"

At the bottom of the article I posted, the author issues this challenge:
"If you are a bodybuilder or strength athlete having verifiable statistics in excess of what the equations of this article predict and have competed in a drug-tested bodybuilding contest then, please, contact me and I'll include the information in an ongoing statistical analysis - your name will be withheld upon request. This invitation has been open since this article was first posted (in early 2007 and dating back through it's predecessors to 2000) and remains so. To those who have contributed I'd like to thank you here. I appreciate your honesty and even bravery ...if that's the right word."
At your height, you would qualify. Contact Casey. Let him know what you have achieved.
Incidentally, you are still FAR behind this TT poster. He has gained about 75 pounds of muscle:
