solid motor mts breaking block?

1 thing to mention is you need to bolt the ears separately from the mounting brackets to the block. If you try to run 1 bolt through the mounting holes that goes through the ears...... YES you more than likely will break off one of the ears on the block.

So if there are 3 or 4 ears on the block you need to use separate Nut Bolts to mount the bracket to the block. DO NOT USE 1 LONG BOLT. When tightening the long bolts you will put stress on the ears and more than likely at some point the ears will snap off.

Stock brackets you almost have to use separate hardware. Custom brackets etc is where someone could make a mistake.

Guy at the engine dyno one time caught the guy setting up my engine doing this. He told him don't ever do that cause you risk the chance of breaking off the ears on the block.
