Price, a bronze-medal winner at the Beijing Olympics four years ago, will meet the 40-year-old, who won gold in Sydney in 2000.
"Audley was an inspiration to me when I was younger, someone our amateur squad always looked up," said Price.
"He called me before Beijing to offer advice, which I'm grateful for, but he's still getting flattened."
Price went so far to sugges that his blueprint for success as a professional will be to do the opposite to Harrison, who failed in a world-title challenge against David Haye back in 2010.
Harrison has flopped miserably since banking £1million from the BBC upon joining the paid ranks, reaching a nadir with his atrocious three-round defeat to Haye.
The fanfare greeting Price's arrival from the amateurs was far more muted, but the big-hitting 29-year-old has impressed during his 13 victories.
"I'm surprised Audley hasn't achieved more and it's a shame he hasn't because he has the talent," Price said.
"He more or less wrote the book on what not to do when he turned professional.
"He took too much on like promoting and managing rather than concentrating on what he's good at.
"I've looked at what he did and told myself I'd do it like this instead.
"I've got a massive hunger to succeed which Audley didn't. He was a superstar as soon as he turned professional, I haven't been, I've had to work for it."
Price admired Harrison after his Olympic success in 2000, but is ready to extinguish the dieing embers of his career in his voluntary title defence.
"I never thought I'd fight Audley because when I was growing up on the GB team everyone looked up to him," he said.
"That was especially the case for me because I was a super-heavyweight and he won an Olympic gold.
"He was bit of an inspiration and I'm not afraid to admit that.
"I looked up to him and he called me before Beijing to give me some advice.
"I have 100 per cent respect for him and I've never been one to call him 'Fraudley' or 'Ordinary'.
"But come fight night I'll be there to do a job. Domestically I'm like a runaway train that won't be stopped. Anyone who does get in the way will be run over."
Harrison will never escape the humiliation of his feeble third-round stoppage by Haye, during which he barely threw a punch.
But the 40-year-old, who has lost five of his 33 fights, won his last outing against Ali Adams inside four rounds and is likely to provide Price with a good test.
"It's a big fight between two massive heavyweights," Price said.
"One's a big name in the UK whereas I'm coming through like a steam train, getting rid of people in my way.
"People are judging him on the David Haye fight and fair enough because he stunk the place out.
"But anyone who can hit as hard as him is dangerous."
Harrison failed to attend the press conference in central London called to announce the fight, but declared in a statement there would be no repeat of the Haye fiasco.
"On a few occasions I haven't shown up which has really hurt my reputation, but I will show up in Liverpool," he vowed.
