Having recently completed major capital investments and added staff, Borowski Race Engines, Inc. is broadening its scope to include Big Block Chevy engines. The company had focused on LS engines in recent years.  

Borowski’s new BBC product line will build on its long-standing relationship with Dart Machinery, as Borowski will be using their Big M (billet steel main caps) and Sportsman blocks (ductile iron main caps) in a 4.560" bore diameter. Borowski’s Sportsman blocks will have a BBC standard deck height of 9.800”, while the Big M's will be tall decks at 10.200".

The rotating assemblies will feature Callies Performance Products crank and rods with Diamond Pistons. The Sportsman block builds will use Callies Compstar crank & rods. Diamond Pistons will provide a range of products with various compression ratios and design features for specific naturally aspirated and boosted engines, the company said.

The Big M blocks are intended for heavier boost, Borowski added, and the tall deck will be utilized to incorporate much stronger parts appropriate to the task.

The parts and assemblies used in these engines will be available for sale to Borowski’s retail and trade customers. In addition, the company will be offering custom BBC engines built on these available foundations to cover street, marine, and a range of race applications.
