And the added 428 crank (that the add states) makes it a 454CID monster, common swap back in the day but even more rare these days using original parts.

I heard once that doing this swap is nearly impossible because the 427 is internally balanced and the 428 is externally balanced and the motor would shake itself to death. Just "what i heard" though...

Onky if you dont bother to use the 428 flywheel/flexplate.
