Default manually turn crankshaft

with engine out and plugs and belts removed how much effort should it take to rotate a 454 crankshaft clockwise ? Not a new or rebuilt engine.

I rotate my 525EFI with a 3/4" socket on a 3/4" drive ratchet. Piece of cake.

I can tell you that you will never get one to turn over by hand with the rod sticking in the side of the cylinder. Been there, done that!

No doubt. Once you hear it going with a stocker just leave it pinned til chit happens. When you come to a abrupt stop and look under engine and see oil and antifreeze/water - not a good sign but on the flip side time for new build and more power. Lol... usually results in a nasty hang over also.

I had one I could litterally stick my entire hand through the oil pan.
