How good is the Vortec 4200 engine?
The Vortec 4200 has a 10:1 compression ratio that helps it achieve impressive power levels. The engine produces 90 percent of its torque from 1,600 to 5,600 rpm running on unleaded fuel. This is due in part to good combustion-chamber design and the cylinder head's ability to efficiently transfer heat.Dec. 1, 2001Chevrolet Vortec 4200 Inline Six Engine - Chevy High Performance
