Fighters with bottomless gas tanks

[goblin213]

Bennie Briscoe
Salvador Sanchez

[Forza]

Take the special drink out of pryors corner and he has a normal gas tank

[Turbo B]

Aaron Pryor.

Edit: "Just saw the hater above me."

[The Surgeon]

Homicide Hank Armstrong is the first name that springs to mind

That slow heart beat...

Just finished watching him fight fellow great Lou Ambers flat out for 15 hard rounds, cant see todays lads managing that *****!

[Feint]

Greb was already mentioned, but I have to write it again just because of how amazing he was.

Calzaghe also deserves a nod.

[The Surgeon]

Of todays fighters ive yet to see Floyd Tire. Sure he often fights within himself but going by his training sessions u KNOW he has plenty in the tank, his calm and confidence help him from tiring too

[Pastrano]

I'm surprised nobody mentioned JEFF FENECH, perhaps the most tireless fighter in history.

[fitefanSHO]

Gatti.

He always had a little something left it seemed.

[Dynamite76]

Ray Mancini
Aaron Pryor
Harry Greb
Henry Armstrong.

[Bolo Punch]

Not on the top tier in terms of skills but pre-2000 Wayne McCullough could take all kinds of punishment and continually bring the action to you for the full 36 minutes. I think his standing heart rate was in the 40s (BPM), or something freakish like that.
