Read The Year Babe Ruth Hit 104 Home Runs. It's a book that goes through, in exhaustive detail, every single dinger the babe hit, with distances for the long ones, plus notes a lot of 420+ foot outs in the big ballparks of the day. The summary is that he hit way the fuck more than 714 using modern rules. Over 1000 was the final tally, but if I recall correctly, that included exhibitions. I need to re read it.
Notably, the Babe's detractors don't note that there was no batter's eye, that run scoring and home run totals were lower then, and he hit 400 and slugged over 1.000 against top Negro League pitching, so he wasn't just dominant in the bigs. In 1927, in modern Yankee Stadium dimensions, he would have donged 85 homers. He had a bunch of 420 foot outs and 450 foot doubles.

Jenkinson has done conclusive research, over the course of decades. Take a look at the book The Year Babe Ruth Hit 104 Home Runs.
Objectively, the Babe hit dozens and dozens more homers due to that rule and cavernous outfields. He has a few more conclusions, but they're slightly subjective. For example, he thinks The Bambino's totals would not have significantly changed if baseball had been integrated, since he batted even better against Negro League teams. Remember, the Sultan of Swat was a barnstormer (even during the regular season), and he would play against anyone, anywhere. Jenkinson looked at 38 games he played against Negro major leagues teams' best pitchers, including, yes, Satchel Paige, and the King of Crash slugged over a thousand.
