IDK, weve never done it BUT I think when you look at PRW , ati, tci, atp etc for aftermarket flex plates they do NOT have listing for gen v/6 cast crank vs forged crank for a flexplate for a hotrod/street car, just the same part #, maybe they split the difference, IDK, Smitty

:NOTE 2: Cast crank only - 41.95 oz. in.
NOTE 3 Forged crank only - 42.54 oz. in.
and has a different column then seperate listing for EACH, BUT goes on to assign them the SAME part # : 915541

So, I just downloaded the 2023 catalog and it looks like they have done away with the external balance ones for the Gen 5-6 ??? All they show is the 541 which is internal balance.
I have to call them today and order some damper parts. Ill ask them and see what they say.

Interesting. My print catalog shows 915541 is for internal balance. 915552 (forged) and 915553 (cast) are for external balance. I dont see the 552 and 553 in your link.

Ok, I talked to ATI a few minutes ago and they did away with the flex plates because there was no demand for them. I guess if you think about it any marine application would be a manual trans type flywheel anyway. Most performance and race Big Blocks that I do are pretty much internal balance so there is no need there either. And if you are balancing the assembly anyway I guess it does not really matter which one you use as long as you make note of it for future replacement.
