Hello Bud put up a heroic performance to make all the running over an extended four miles in the Coral Scottish Grand National at Ayr.
The 12-1 shot, ridden by Paddy Brennan and trained by Nigel Twiston-Davies, held the late thrust of Tony McCoy on Gone To Lunch (12-1).
Out The Black (12-1) and Chiaro (10-1), both trained by Philip Hobbs, were third and fourth respectively.
King Barry kept Hello Bud for company in the early stages, while Out The Black, Coe and Brooklyn Brownie were all close up.
Arteea was pulled up in the rear before the field went out on the final circuit, with That's Rhythm a faller.
Hello Bud fended off all challengers up front and though Gone To Lunch came with a late flourish, McCoy's mount was half a length down at the line.
Brennan said of Hello Bud's half-length triumph: "He loves it. I've not won on him before so David England takes a lot of credit.
"I've got the best boss in the world and he keeps on producing big winners.
"What a fantastic season and this is the icing on the cake."
Twiston-Davies, who was winning his third Scottish National, said: "He's won all of his races from the front and he did it beautifully.
"It's a great effort and I'm absolutely chuffed to bits.
"We'll look at the Becher Chase and things like that, but we've got to think about the Grand National, the English one, next year.
"We've got great riches in that department and it's so exciting."
