It's as good as any other roller block and it will be fine for most uses.
If you plan on high HP, TC or SC then I would go with an aftermarket 4-bolt main block if it fits your budget.
I don't know what the other letters mean, sorry.
Do a search on Google for 5.0 engine block number or tags decoding and you may turn up some explanations.
