402 or 454?

I am going to be swapping out a blown 402 big block with a new longblock, and was thinking of going with a 454 instead...all the accessories will bolt up. I was wondering what I would need to change? Do I need to change the flexplate? The 402 is bolted up to a 700r4. I know a flywheel is balanced to each particular engine. I know I will need a different harmonic balancer. Anything else? Thanks!
