Dickson was named Best Boxer of the Show as he outpointed Fifer Tom Brunton last week on a Cardenden club show bill and coach Terry McCormack has high hopes for his boxer.
''David was outstanding at the Cardenden show but now he means to use his Best Boxer award as a springboard for winning an Eastern title on Sunday - he's in great form just now.
"Similarly, I have title hopes for our ex-Scottish champion Steve Tiffany, who is boxing at featherweight and, of course, if light-welter Lewis Benson produces his best form then he too could win a title on Sunday.''
Also boxing for Lochend in the Bowhill championship event will be heavyweight Stevie Nicholl and welterweight Tommy Philbin. Meanwhile, Leith Victoria coach Ray Gibson was cautious saying: "While our lightwelterweight, Sean White, lost his Scottish title final to Fifer Connor Law earlier this year competition at his weight of 64kg is going to be ferocious with Lochend's Lewis Benson a hard guy to beat, but Sean will give it his best shot.
"At lightweight, although our boxer Brian Lacey will be a massive underdog if he draws Craigmillar's current Scottish senior champion Jason Easton, Lacey will come to do his very best.''
Craigmillar coach Kenny McCartney sees these championships as a road to ring redemption for Jason Easton, saying: "Jason is desperate to restablish himself after being beaten by vastly more experienced English opposition in the recent British championships in Liverpool and our lightweight Tony James has also been looking sharp in training.''
The boxing at Bowhill will start at 1pm.
