A 727in³ — just over 11.9-litre — EFI custom-built ‘hemi’ engine from Sonny’s World Class Racing is the prize in the 2018 Sunnen Engine Charity Sweepstakes at the Performance Racing Industry show, being held at the Indiana Convention Center in Indianapolis 6-8 December.

The engine can be ‘street-driven’ on 93-octane fuel and produces 1,310hp naturally aspirated.

Sonny Leonard and his team (based in Lynchburg, Virginia) have volunteered to build this high-performance engine — worth more than $60,000 — for what will be the 30th anniversary of the Sunnen Engine Charity Sweepstakes.

All proceeds will go to the Victory Junction — a camp (founded by NASCAR’s Petty family) for children living with serious medical conditions.

Over the past 30 years, Sunnen Products Co, PRI and many well-known engine builders have teamed up to raise hundreds of thousands of dollars for charities within the racing community.

Sunnen has been a global leader in the manufacture and distribution of bore-sizing and finishing equipment, engine-rebuilding equipment, tooling and abrasives since 1924.
