I have a complete 347 rotating assembly fresh diamond pistons eagle rods/crank yada yada I have a xxx block that came with it it's already .030 over but I have a xxl block that was in the car that is completely stock is the xxl block worth getting the machine work on or should I just stick with the xxx block?

if it were me i would run exactly what you got from me, your only looking to make about 450hp right? if so that setup will be fine. But to be honest i dont even know the differences in the 2 blocks except that i think your old one is a non roller block
