My birthday isn't until next week, but my present arrived today! New 408 ci engine from Carolina Machine Engines. The dyno sheet is showing 463 HP and 493 torque. Can someone help me decode the spin sheet as it appears to show a bobweight card for rods, pistons, pins for left and right side with 2 spins? I've not seen one of these before so I will take as much information as you can decode.
