Question

In MLB since 1970 on record who has hit the Longest home run and how long was it?

Answer 1

Dave Kingman. 513' It was a GREAT historical moment So that is who I think it was and How long I thought it was

Answer 2

My guess is Dave Kingman.  513'

Answer 3

You can't really answer this question without getting scrutinized for it.  It's a hard question to answer cause its all speculation and not an exact number. but in my mind it was definitely Reggie Jackson '71 All-Star Game 0-2 count monster shot that hit a light tower, I couldn't tell you the distance but that's what I'm thinking.
