thats why chevy and ford upgraded the low revving straight 6's to 7 main bearings. .. its force that bends metal. while it will happen at high rpms, as there is more force, it will happen at low rpm also, if the pistons are producing force. ever see a low revving diesel 6 with 5 main bearings? no modern engines have the 2f design. its 1930's cost saving technology.
nickle is added to refine the structure and add toughness and wear resistance. pure iron is brittle. it has nothing to do with weight. maybe we should make engines from lead.
Holy crap. You do like to argue just to argue.
Adding nickel to an engine makes it heavier hence it ways more. Adding Nickel makes the block stronger. You're right, 2fs are a complete garbage motor.
