A 727-in3 EFI custom-built hemispherical engine from Sonny’s World Class Racing is the prize in the 2018 Sunnen Engine Charity Sweepstakes at the Performance Racing Industry (PRI) show.

The engine can be street-driven on 93 octane fuel, producing 1310 hp, naturally aspirated. This will be the 30th anniversary of the Sunnen Engine Charity Sweepstakes, with all proceeds going to Victory Junction, a camp founded by NASCAR’s Petty family for children living with serious medical conditions. The winning ticket will be drawn at the PRI show in Indianapolis in December.
Valued at more than $60,000, the engine will include: Sonny’s fully in-house ported hemispherical cylinder heads, Sonny’s/Brodix 5000 BS block featuring 1” raised cam with special high-flow water jackets, a Bryant billet crank, Carrillo steel billet rods and much more.
Over the past 30 years Sunnen, PRI and many well-known engine builders have teamed up to raise hundreds of thousands of dollars for charities within the racing community.
