If we then do HR Rate/SO Rate we get 204/49 = 4.16. That leaves Berra 4th all-time. All data from the Lee Sinins Complete Baseball Encyclopedia.

Now Berra did hit 210 HRs at home in Yankee Stadium, which was a great park for HR hitting if you were a lefty. But if we double his road total of 148 we get 296. If we divide that 296 by the league average of 175, we get a HR rate of 169. If that is divided by his SO rate of 49, we get 3.44. That would still leave him 11th.
Maybe Yankee stadium also cut down on his strikeouts. I don't know if it helped batters in that way. I also could have given him more than 296 HRs, since players usually hit more at home no matter what.
If we adjusted DiMaggio, who hit 213 of his HRs on the road (Yankee Stadium was tough on righties), his ratio would rise to 5.56, putting him ahead of Ken Williams.
DiMaggio hit only 41% of his HRs at home in his career while Williams hit 72%. So it is likely the case that DiMaggio would rank first, and probably by a wide margin, if HRs were park adjusted. Ted Williams hit less than 50% of his HRs at home.
