		Yes, balancing is very important (even on a cruiser) when going to the 428 crankshaft.  The 428 shaft is externally balanced (there is weight added to the flywheel)  while the 390 is internally balanced.  If you are doing a crankshaft swap, I recommend taking all parts to a good machinist and having the 428 shaft internally balanced (usually 2 to 3 small pieces of mallory metal added to back counterweight of shaft), unless you have the balancer and flywheel that came with the 428 shaft.  In this case, I would still have it balanced, but the work/cost should be minimal.  I normally pay between $150 and $250 to have 428 shafts internally balanced, and all other parts balanced.
