New flywheel balanced to match balance sheet?

I have run or drove both in big and small block and i will take a heavy wheel any time.I think some automatic trans drag cars use a heavy wheel to help not sure on the auto thing but i think i saw it somewhere. I am a stick guy and dont give autos a second look.

It's a dual quad 428. Factory MR intake. Edelbrock heads. Flat tappet cam with 232@ 50 and 242@ 50. 5.87 lift on 112 degree lobe center. 10.0 compression. 3.50 gears, 2.78 wide ratio four speed.  WT 3156.
That should give you a bit more to work with.

You'll be much happier with the heavier flywheel,though I might not go all the way to 40 lb,I swapped from a stock weight flywheel to a 40 lb aftermarket on my 427 which with the stock wheel was really snappy with throttle response both going up and down with rpm's but with the 40 lb wheel it was much less responsive,I will be going back to the stock weight wheel which is still twice the weight of your aluminum flywheel.The 40 lb flywheel definitely gives the shot out of a cannon sensation but the stock weight wheel pretty much did too.
