today I was just about to order my crank kit when I noticed in the description that it has an externally balanced crank... well, one of the options I checked off was to have the whole kit balanced. wouldn't they need the damper and flywheel to do this? I've been reading old posts and articles on balancing and now I only feel more confused than ever. if I have a 454 should I be looking for an internally or externally balanced crank and why? and what damper and flywheel do I use? I have a flywheel off a sbc 350 and I just assumed it would work on my BBC, but a friend told me recently that my thinking was just insane... I'm starting to think maybe I should go back to my 427 crank; things seemed like they made more sense. I know this is alot of questions, but the bottom of this engine has me so confused. am I making this harder than it is?

Buy a damper and flywheel from the same folks and have them balance it as a complete assembly before it's shipped.

Why not just opt for an internal balanced 454 crank...?

well, I don't know why not, I was hoping someone would tell me.

Order your kit without balancing and have it balanced locally with your damper and flywheel. I get them done for $150

If it is a flexplate (automatic) then they should be interchangeable from SBC to BBC as long as they are both internally balanced.

If you have the option of getting an internally balanced 454 assebmbly, get it. An internally balanced assembly is preferable to an externally balanced assembly because it imparts less stresses on the crank and is easier on main bearings. Plus, you will be able to use your 350 flywheel, as well as an internally (neutral) balanced harmonic balancer (like the 427).
