that is a waste of money it is know fact that a stock 5.0 block can handle 500+ hp no problems just dont go over 550. A used block is the way to go because all new blocks have to be machined unless the retailers state otherwise.

the info on that block says it is already machined for stock 4.000 inch pistons so it won't need any machining. the choice is up to you on what to do for a block as it all depends on how much HP you want to make and how much money you have to spend on it.
