Jason, the 40mm has a safe working load of 150lbs with a breaking load of 300lbs..  Any issue with the block?  The 57mm is 300 an d 750.

I haven't had an issue yet, but it would be very easy to swap if I ever needed to. I did keep the top clam cleat too (still worn), which might help a little bit.

It is certainly larger than the previous block!

If you run the halyard around the side of the cleats while hoisting it doesn't wear out the cleats. Then when the main is fully hoisted put the halyard in the cleats for securing.

Boat #22 has a jam cleat paired with a horn mounted a little lower down. Jam cleat holds it well enough until I can get it around the horn.
