“... we’re making significantly more horsepower than we were making last season.” “We’re definitely moving in the right direction.”

Mario Orsini Set to Return to NMCA Pro Street with Rebuilt Engine: 

“I took the engine to Borowski Race Engines and for the rebuild, they used the block and the Alan Johnson head castings, but got a new Bryant crankshaft, R&R rods, Diamond pistons and Bullet camshaft. This is the first time in thirty-three years I have let someone else build an engine for me, so that says a lot about Borowski Race Engines.”
