Ok, got a 331 stroker that I need to put on the engine stand. Aluminum heads already installed, complete long block but no intake on it. What is the best way to lift this motor with a hoist? I am uneasy about bolts into the aluminum heads as I fear they will break or strip the threads and pull out. Am I being too concerned and should be fine? How do you all lift your motors? Lastly what is the bolt/thread size for the intake to heads and the back of the block where the bellhouseing bolts where I will bolt it to the engine stand? Please help as I dont have much time and need to return the borrowed engine hoist. thanks all in advance.
