BLOWN 510CI BIG-BLOCK

BG ENGINES, NORTH RICHMOND, NSW

- IAIN KELLY

HANDLING the stresses of running wide open on a pad for a minute straight is no mean feat for an engine, which explains why we’ve seen burnout-car donks morph into wild, purpose-built creations.

The tower of power on these pages is a good example. What hides inside this conventional-looking big-block Chev is plenty of smarts that Damian Baker from BG Engines has learned through years of hard work.

“It runs a 9.8in-deck-height Dart Big M block with a 4.5in bore and a 4in-stroke Callies Magnum crank, for 510ci,” says Damo. “It’s the same set-up as what is in [Rodney Waters’s] KRANKY HQ, and the reason for it is to keep piston speed down. You want cubes to make grunt, but this style slows the piston down and holds it in the bore better.”
