Looking for information on a previous owner

[PA_65_Plymouth]

Gentlemen by the name Richard Thomas Browning (I know he’s deceased) but didn’t know if anyone here knew him or had any dealings with him. I bought his 65 Satellite from someone that bought it from his son in law neither of the previous owners knows anything about the engine build
It’s a long shot I know but, it was supposedly built at a shop somewhere in Michigan (Sterling Heights area possibly) appreciate any information
