415 lb-ft torque @ 4800 416 HP @ 5800. This was on the Holley 600 DP. Engine would not idle below 1500 and I am sure there will be drivability issues. Just ran out of time and moola. Much more detail and videos to follow. My butt is worn out and I still need to get the engine out of the back of the Acadia. Duke B382002037
