Building street 408 stock block with 192 high ports and a flat tappet mech cam. Looking at Woodys rotating assembly's.  Stock block mild build with a small shot of nitrous. Do you need the forged crank and h beams ?

I'd think that particular kit is up to whatever the the factory block is capable of.

Some of the other kits on the market? Not so much.

I'd be fine with anything in that kit all the way to the blocks limits. The pistons and rods are very nice, and I've seen Scat 9000 cranks pushed pretty damn hard.

The Eagle and many other kits aren't nearly as nice as Jim's.

Two ways to look at this, either the rpm internal steel crank is woefully under priced or the cast scat crank is woefully overpriced. The quality difference between the two cranks is night and day. They are not even comparable from a value stand point. What sucks is when you end up with a junk cast crank, you have to ship it all over the world and try again with another one. I have never had to send an internal rpm crank back, they are that consistent and good, its pretty scary honestly

Will the internal balance help block last or will the rotating assembly be heavier ?

Sure the rotator will be heavier but its of zero consequence. Look at what you get for your money. Value should always be one of the first thoughts. Not the actual cost but what do you get for the cost. The cast crank is a pile of crap compared to the rpm internal steel crank.

The internal balance has the weight on the inside where it should be vs the cheap external balance that has the weight on the balancer and flywheel ends causing the crank to flex which is much harder on the block.
