Can a 400BBM w/cheap aluminum heads compete/dominate against the street LS?

OK, here is my catch. What is competitive in your neck of the woods?

Competitive in my neck of the woods mostly includes late model mustangs, some vets, old muscle cars, and LS swap’s, and small block Chevy builds.

Would piston replacement be on the table?
Is a stroker kit on the table?
Or are we just working with a stock stroke low compression 400?

Definitely pistons, appropriate machining,

only considering low compression with turbos-but again it seems like $$ pressure management $$ is computer controlled expensive;


It sounds ignorant, but I have heard on multiple occasions that the BBM make so much torque that they can break the block (especially large strokers),

a 451 or 470 seem awesome, also like a rabbit hole of upgrades and expenses (I have never found a machine shop with mopar torque plates;

and then stud girdle, aftermarket caps, torque plates, I am not sure what else, plus a few more things and I probably only know the beginnings of a high output engine.
