Unless Eagle do a specific internal balance crank for your stroker combination I think you may have to settle for external balance. I made the mistake of balancing an Eagle crank internally and there simply wasn't enough counterweight material to do it economically ( ended up using a huge amount of heavy metal and costing £1500!). The stroker spec makes this more demanding. If it is a two bolt block then a mains girdle will help if you want to see 7k rpm. Or you could get billet caps for nos 2, 3 and 4 and line bore the block ( in some ways a better idea than honing).
