Big Blocker won't be retiring after Saturday's Blowes Clothing Cup grand final... no matter the result.

While he recently enjoyed his 37^th birthday, the decorated Lions forward is feeling in close to the best shape of his career and has his sights set on not only another top-flight chip, but the all-time first-grade caps record, currently held by Anthony Sullivan with 210.

When he runs onto Wade Park on Saturday, he'll equal that record and plans to knock it out of the park in 2021.

"At this stage I'm still going to go on," Tremain said.

"I don't play for accolades but that would mean a lot to me. I honestly just feel like I want to keep playing.

"Nigel's [Staniforth's] 40 and he's still doing it... maybe next year will be my last but we'll see what happens."

But before Blocker makes any decisions about retirement, he's got to focus on the all-important grand final against Emus, a fixture he didn't think he'd be a part of again.

"I didn't think I'd play in another first grade grand final," he said.

"The nerves haven't hit yet, but they will. It's taken so much work for us to build up to this."

He didn't think he'd play in another first grade final before this season started but he also thought his chances were shot with about three minutes left in the preliminary final match at Dubbo after he committed a rare error in attacking territory with the game on the line.

"I was shattered after that," he said.

"No one from either side said a thing... I was devastated. He just hit plum on the ball and popped it out.

"I asked the ref how long we had to go and when he said three minutes, I thought we still had a chance."

As it turned out, Kieran Bonin crashed over the match-winning try and the rest is history.

The focus for City now shifts to Emus and more specifically for Tremain, that formidable pack led by Charlie Henley.

The Lions know they're coming up against arguably the benchmark group of big men in the league but Tremain's plans for the finale is to out-enthuse Bromley's boys.

"We're coming for them, he said.

"It's about us bringing our A-game, our belief, and our intensity.

"We've got to keep the throttle on from start to finish." Saturday's decider will kick-off at 4.30pm from Wade Park.
