A bare Chevy 350 engine block weighs about 200 to 250 pounds. When you add in the crankshaft, camshaft, headers, and the intake it is more like 500 to 550 pounds.

That is because of the way the gear on the distributor and camshaft is tapered. If you turn it the other way it will pull the camshaft towards the rear of the engine. That is all normal. When you put it all together it won't do that.
