I think they just list it that way since 427 stuff isn't searched for much.

i have a 489 in the shop that i am rebuilding,i finished the disassembly today ,it has a forged scat crank and it is externally balanced.they offer it for folks that don,t want to replace the existing balancer&flywheel.it was built 13 years ago and the assembly was balanced at a machine shop,i know this because the shop that did the balance job scribed their name and the bob weight and the date it was done on the crankshaft.
OP should contact where he got it from and just confirm what is what and go from there. He might get lucky.

Doesn't surprise me at all. Honestly I think all those stroker assm kits should be internally balanced. I would never trust an already so called balanced kit anyway but that's just me. Easy to drop off flywheel and balancer at machine shop to have them neutrally balanced.

Just from my build, I went with the eagle forged crank kit. I went with the externally balanced. My machine shop recommended what flywheel and balancer to go with. I had him put it together and balance everything. I know you already have it together but I would take it to a shop. You can't beat having proven data that it spins smooth and all the clearances check out. Also I found all dyno guy that was 500 to run it for 4 hours. In my opinion the everything Xtra $ spent is all for the piece of mind. This way I know that it is together and running correctly. This way I don't have to build it again and spend 10x the amount I spent to do it right the first time. Again just my opinion but pull it and spend some money to save a lot of money.
