GM 604 Crate Engine Becomes IMCA Modified Option In 2013

January 1, 2013, marks the introduction of division-wide allowance of the GM 604 crate engine by IMCA Modifieds.

It will be the first time in the 35-year history of the class that an engine which cannot be claimed is allowed in sanctioned competition.
Modified drivers can continue competing with a claim engine.

Crate engines are already options for drivers in the IMCA SportMod and Hobby Stock divisions.

The crate won’t be legal for use at any sanctioned Modified event in 2012, such as the IMCA Speedway Motors Super Nationals, JR Motorsports Hawkeye Dirt Tour races or the Duel In The Desert.

Any 604 motor used next season will be required to have GM tamper-proof seals and IMCA seals.
