He included the two preliminary final wins over the Western Bulldogs in those memories, when the Croweaters crossed the border into Victoria as underdogs, only to eventually take the premiership trophies home with them.
But, with three preliminary finals losses already under his belt, Johncock is sick of reminiscing about the achievements of others.
He wants his own history.
"Being a Crows supporter growing up, obviously the '97, '98 Grand Finals stand out, even the prelims against the 'Bullys'," Johncock said.
"Those were pretty exciting, so hopefully I can build some memories of my own because at the moment we've gotten so close, but yet so far.
"I'm really looking forward to this week, it's another opportunity to play in a Grand Final so hopefully we'll go alright."
Parallels could certainly be drawn to Adelaide's current situation and the one it found itself in at this point in '97.
Hardly given a chance, the Crows fought back hard in the second half of the preliminary final to scrape home over the Bulldogs by two points.
Assistant coach Mark Bickey said the current side was a bigger underdog than that team, but Johncock said Hawthorn's overwhelming favourtism and the immense expectation to easily account for the Crows could work against it.
"That's got to put a bit of pressure on Hawthorn, I think they're $1.80 or whatever it is in the betting and stuff like that," he said.
"It's going to be interesting to see how they handle it, so nobody's giving us a chance but deep down inside ourselves, the way we prepare, we think we can beat anyone."
Johncock turns 30 in October and, with the imminent retirement of his teammate Michael Doughty, he said he knew his time to write his name into Adelaide's history books was running out.
His body didn't do him any favours in 2012, with persistent hamstring and back issues hampering his move into Adelaide's forward line.
After spending significant time playing for Port Adelaide in the SANFL this season, Johncock admitted he occasionally thought about when the time would be right to call it quits.
But he said in his current situation, on the eve of a preliminary final, retirement was far from his thoughts.
"It does cross your mind every now and then, but you try to forget about that stuff," he said.
"The situation that we're in, it's good just soaking it up and going full bore.
"This is what you play for, this is my 12th year and my fourth time in this situation and still yet to go that one step further into the GF, so hopefully this year's the year."
