Don't know your setup, but torque straps to one of the mounting bosses is never a good idea.......
I don't get why the passenger side would be cracked also though....unless....do you have rigid straps on both sides ??
Where should they be attached? I never considered the motor mount boss wouldn't work given that's what point the factory used to hold the engine.
The original mounts were bolted to 3 points on each side....if u have rigid straps going to only one of the bosses.....that's where the problem lies imho
To me its the angle of how its loaded.. in other words if you pull from the side of the block as in a torque strap its not bad... but if you load from the front of the engine as in engine limiters(limiting the front/back movement) the load then applied to mount ears is amplified by the 2" or so that the ears stick out off the block and that would load the block 90* to what it was originally designed for.... I load the ears on my SB at a 45* angle which is 1/2 the load on the block... but from what some are saying its just a weak block
