According to their chart, the proof load for a Grade 2, 1/4in bolt is 55,000 psi. Accounting for the threads and using an approximate diameter of .2in, the grade 2, 1/4in bolt should support 1700lbs without deforming. That is only one bolt and it's a small diameter and a low grade. So these should work fine to support an engine, assuming the threads don't fail.
