what about the balancing. Are lt1s internally or externally balanced?

They are all internally balanced. Only the 400 SBC was externally balanced. 87+ Small Blocks (including LT1s) are internally balanced regardless of what people tell you about the weight attached to the flywheel on manual cars. Someone convinced me otherwise once and it cost me a 500$ flywheel.
