We installed a flow master exhaust system and started the rebuilt engine for the first time. Broke the engine in for 20 minutes at about 2400 RPM and the goose bumps were a plenty. My son was so excited he could not stand still. We could not get over how nice a deep rich tone that 351W was making. Have not got it ready to move yet. Still got to bring the power brakes and power steering online before I can move it. But what an exciting and gut wrenching moment to hear that beauty purr for the first time!!!
